---

QIAGEN RNA-seq Analysis Portal 4.1

Released August 2023

New Features and improvements

• For miRNA analyses, a new “piRNA matrix” is available via the Download expression values functionality on the Samples tab of the Experiment summary and QC report. The downloaded file contains identified miRNAs and piRNAs across all samples in the experiment.
• The maximum file size limit in the sample data uploader was increased from 50 GB per file to 70 GB per file.
• For miRNA Quality control, the “Records found in sample” metric was removed.

Bugfixes and other changes

• Fixed a bug where applying multiple filters in a differential expression view could cause the feature table to look empty.
• Fixed a bug where Biological Insights filters for miRNA analysis results for mice and rats could display zero features even though relevant features were found.

 

QIAGEN RNA-seq Analysis Portal 4.0

Released February 2023

New Features and improvements

• The QIAseq FastSelect Lib Kit has been added with three protocol options, one for each DNA synthesis protocol available for the sample kit:
  • QIAseq FastSelect RNA Lib Kit (N6-T RT primer)
  • QIAseq FastSelect RNA Lib Kit (ODT-T RT primer)
  • QIAseq FastSelect RNA Lib Kit (N6-T RT + ODT-T RT primers)
• For QIAseq UPX’3 Transcriptome kit and the UPXome RNA Lib kits, analysis of already demultiplexed data is available if you select two or more sample data sets.
• For “QIAseq FastSelect RNA Lib Kit (N6-T RT + ODT-T RT primers)” and “UPXome RNA Lib kits (N6-T RT + ODT-T RT primers)” samples, the Quality control report will have separate sections for each of the two sections in the analysis workflow.
• Onboarding pop-ups have been added to assist first-time users in getting started using the Portal. Clicking “Don’t show again” will hide the messages. Pop-ups can be re-activated from the Help menu.

Bugfixes and other changes

• An option to upload sample data in a separate browser tab was added. This improves stability for uploads that run over an extended period of time.
• On the Differential expression view it is possible to click on “Start now” under “What’s next” without first having separately saved the view as a filter.
• On the Differential expression view, sorting of the feature table is maintained if you switch between table and grid view.
• The volcano plot y-axis will change with the selection between FDR p-value and p-value.
• The volcano plot y-axis shows two decimals.
• Biotype charts now have a minimum width relative to the number of samples. In an experiment containing many samples, the bar charts in the QC report will have a horizontal scrollbar. In PDF/print view, the plot will be scaled down proportionally.
• Improved support for sample lists in various dialogs on smaller screens.
• Fixed a bug where the sorted order of unmapped reads in the taxonomic profiling for contamination detection was not correct. They are now ordered with higher values at the bottom in the stacked bar chart.
• Fixed a bug where renamed experiments did not display the new name.
• Fixed a bug where experiments using ”%” as part of the attribute names could not complete the Biological Insights filter part of the analysis.
• On the Quality control tab, the “Strand specific setting” shows as empty when no reads are mapped in the Align and count process. Previously it incorrectly displayed “0”.
• In the Help menu, “About QIAGEN RNA-seq analysis” links to the product page for RNA-seq Analysis Portal on GeneGlobe.
• Updated cookie acceptance and cookie management.

 

QIAGEN RNA-seq Analysis Portal 3.0.1

Released November 2022

Improvements

• In the sample kit dropdown, the QIAseq UPXome Lib Kit item has been replaced by three new QIAseq UPXome Lib Kit entries, one for each DNA synthesis protocol available for the sample kit:
  • QIAseq UPXome Lib Kit (N6-T RT primer)
  • QIAseq UPXome Lib Kit (ODT-T RT primer)
  • QIAseq UPXome Lib Kit (N6-T RT + ODT-T RT primers)If you analyzed data with the previous QIAseq UPXome Lib Kit element, we recommend that you rerun your data with the relevant new sample kit item.

Bugfixes and other changes

• Fixed an issue where fold change values for differential expressions with experimental setup All group pairs would sometimes be the opposite direction to that intended, see

QIAGEN RNA-seq Analysis Portal 3.0

Released July 2022

New features

• Integrated upload. Upload of data now happens via a dialog within the existing browser tab. Previously, you were taken to a separate tab. You can monitor progress of your file uploads via the Uploads icon next to the Help menu. Once an upload is done, you can proceed to the Align and count dialog with the sample data pre-selected.
• Connected dialogs for improved analysis flow. You can proceed from the Align and count dialog to the Create experiment dialog with your new samples pre-selected.
• Contamination analysis. For RNA samples with more than 25% unmapped reads, an additional taxonomic profiling analysis is performed to test for potential contamination from bacteria and archaea.
• lncRNA analysis. For RNA experiments, the differential expression analysis will include both protein coding and lnc_RNA genes. On the Differential expression view, the feature table will indicate the biotype. You can filter on biotype using the new Advanced filters functionality.
• Advanced filtering. On the Differential expression view, the Advanced filters functionality allows you to filter on biotype and CPM expression values.
• A demo version of the RNA-seq Analysis Portal can be accessed without the need for login. This allows users, who do not have a My QIAGEN account, to get a feel for how you would upload data and start analysis, and how analysis results are visualized.

Improvements and changes

• For RNA sample kit data, the expression value downloads will contain CPM values.
• The application will support creation of experiments with up to 2x 384 samples.
• The Align sample data analysis time has been reduced by approximately 50%.
• In the Align and count dialog, BaseSpace access will no longer trigger browser pop-up blockers.
• On the Experiment summary and QC report, the Biotype distribution chart and table will have biotypes listed in alphabetical order.
• On the Differential expression and Comparison views, the feature tables are sorted on Name. Also, the ‘Sort by’ dropdown will reflect sorting on table headers, and vice versa.
• On the Differential expression view, a Reset button allows you to set filtering to default values. Previously, this was done via the filter dropdown where you would select Default filter.
• For QIAseq miRNA Library Kit differential expression results, the Biological Insights category Upstream regulators that for miRNA analyses was always left empty has been removed.

Bugfixes and other changes

• Fixed an issue for the Comparison view where values on the Venn diagram sections would sometimes be over- or underestimated.
• Fixed an issue for the Comparison view where manual selection of features in the table would prevent subsequent feature selection via the Venn diagram.
• Fixed an issue for the qPCR normalization gene view of the differential expression feature table where the message for cases where no genes met the requirements for qPCR normalization genes would incorrectly state that the absence of qPCR normalization genes was due to the samples having been analyzed on an older analysis workflow version. The message for such cases now correctly reads ‘Zero features meet the criteria for qPCR normalization genes’.

 

QIAGEN RNA-seq Analysis Portal 2.5.1

Released April 2022

Improvements

• Experiment summary and QC report: On the Quality control tab, the biotype distribution plot and table will report on all tested biotypes regardless detection. Previously, biotypes would be listed only if detected in at least one sample.

Bugfixes and changes

• Fixed an issue that could cause CPM values exported from QIAseq miRNA Library Kit experiments to be associated with the wrong sample name in the Excel file.
  The issue, including information on how to spot whether your downloaded expression values are affected, is documented at https://digitalinsights.qiagen.com/technical-support/faq/important-clc-notifications/qiagen-rna-seq-analysis-portal-mirna-expression-value-downloads-may-give-wrong-cpm-value/.
• Fixed an issue with the Differential expression view where the Start now button for sending results to GeneGlobe was enabled for the Default filter results. Clicking the button resulted in an error. Only saved filter results can now be sent to GeneGlobe.
• To improve the user experience, the Download expression value ‘multi-sample file’ options are no longer available on the Experiment summary and QC report. The amount of data involved in the download caused the browser to become unresponsive for several minutes and sometimes even crash. The ‘One file per sample’ options remain.

QIAGEN RNA-seq Analysis Portal 2.5

Released March 2022

New features and improvements

• Support for QIAseq UPXome RNA Lib Kit.
• Download graphics. You can download the various plots and charts as .png.
• Download Experiment summary and QC report. You can print or save the report as PDF.
• 15 additional reference species: Thale cress, cow, roundworm, dog, zebra fish, fruit fly, horse, chicken, crab-eating macaque, rhesus macaque, rainbow trout, rabbit, baker’s yeast, fission yeast, and pig. All species are supported for RNA sample kits, 11 of them also for the QIAseq miRNA Library Kit.
• qPCR normalization genes. The differential expression view lists candidate qPCR normalization genes.
• Upstream regulating miRNAs: For RNA sample kit analysis workflows, the Biological insights results Upstream regulators has been split in two: Upstream regulators and Upstream regulators (miRNA). The content of the latter will be sent to GeneGlobe alongside differentially expressed features and Canonical pathways when you click the ‘Start now’ button.
• Changes to existing analysis workflows
  • QIAseq miRNA Library Kit: To ensure considerably faster data analysis and enhance support for large datasets, the Quality control report will report on miRBase and, when available, piRNA annotation records only. If you are interested in knowing what other RNAs are present in your library, you may process your sample with the Legacy analysis pipelines on geneglobe.qiagen.com/analyze.
  • QIAseq UPX 3′ Transcriptome Kit: The demultiplex step will apply the cell ID as suffix for sample naming. Previously, the suffix was based on the well plate row and column. Cell IDs and well plate layout is given in the sample kit handbook https://www.qiagen.com/us/resources/download.aspx?id=28512222-986f-4027-bb45-2c7e65d3fd2b&lang=en .
  • QIAseq UPX 3′ Transcriptome Kit: The demultiplex step allows 1 mismatch per barcode. Previously, no mismatches were allowed.
  • RNA Stranded sample kits: On the Quality control tab of the Experiment summary and QC report, the metric ‘Reads after trim’ covers paired reads only. Reads from broken pairs are not counted as these are not used in downstream analysis.
• Data upload: Lower case file names are supported and will be appropriately grouped alongside upper case file names.
• Differential expression view
  • The Save and go to My projects functionality has been split in two. You now save your filter and send results to GeneGlobe My projects in separate steps.
  • On the heatmap, you can select whether you want to see sample and feature labels.
• Experiment summary and QC
  • The report was renamed from previously Sample and quality control.
• On the Project overview, if a project contains failed samples this is indicated in the Project details panel.
• Project and experiment view
  • Information on the Project view has been rearranged. If a project contains failed samples, the number of failed samples is posted both for the project as a whole and for the individual experiments.
  • On the experiment view, the analysis tiles were made smaller for better overview and navigation.
• Samples overview
  • Names in the Project column are now links. Click a project name to navigate to project view for that project.
  • Improved messaging for failed samples. A tooltip on failed samples will specify if the failure was caused by corrupt data or, for UPX sample kits that no reads have been assigned to the sample during the demultiplexing analysis step. The latter could indicate that the wrong wells were selected in the Align and count dialog.
• Create experiment dialog
  • The dropdown ‘While controlling for’ only allows selection of attributes that are independent of the attribute applied for ‘Test differential expression due to’. This restriction is imposed as the effects of dependent attributes cannot be estimated separately. Previously, selecting dependent attributes was allowed but resulted in an error.
• Link Support submit to existing support case. When you use the Share experiment with Support functionality, you can enter a support case number to link the experiment to an existing support case.
• On smaller screens, certain elements will be modified or reduced in size to improve navigation and optimize use of the limited screen real estate.
• Easier selection of samples. In the various dialogs, instead of having to click the checkboxes you can select samples by clicking anywhere in the respective rows.
• Scientific naming. References are named by their scientific name, for example homo sapiens instead of human.
• Ensembl IDs included in downloads. When downloading gene lists from differential expression and comparison views, or gene and transcript expression values from the Experiment summary and QC report, the downloads will contain the Ensembl IDs.
• For RNA sample kit data processed with the most recent analysis workflow version, the expression value downloads will contain genes and transcripts of all available biotypes as well as a biotype column. For older analysis workflows, only protein coding features are included.
• You find a link to the RNA-seq Analysis Portal Latest improvements by clicking the ‘i’ icon at the bottom of the user interface.

Bugfixes

• Fixed an issue where differential expression results could not be saved and sent to GeneGlobe if the raw p-value was selected for filtering instead of the default FDR p-value.
• Fixed an issue for the Comparison view where values on 3-circle Venn diagrams were overestimated. Genes found in more than one group would be counted towards multiple sections of the plot. As an example, a gene found in both group 1, 2, and 3 were included in the counts for both the appropriate intersection 1-2-3, as well as intersections 1-2, intersection 2-3, unique area 1, and unique area 2. Values on the plot legends were correct. 2-circle Venn diagrams were not affected.
• Fixed an issue with the Rat QIAseq miRNA Library Kit Quality control report where metrics for annotation with alternate databases piRNA, tRNA, rRNA, mRNA, snoRNA, and lnc_RNA/scRNA/ncRNA/snRNA were based on mapping to human sequences, not rat. The impacted QC tables were ‘Annotation records found’, ‘Unique search sequences’, and ‘Reads’. miRBase counts and therefore the downstream differential expression results for miRNA were not affected.
• Fixed an issue with the Create experiment dialog for projects with mixed Illumina sample kit samples. If a project contained both Illumina Stranded Total RNA Prep and TruSeq Stranded Total RNA Library Prep samples, in the Create experiment dialog the presented samples would sometimes be of the opposite Illumina sample kit type than what was selected in the sample kit dropdown.
• Fixed an issue where the ‘You have received one or more project copies’ notification pop-up would duplicate as you migrated between pages. As a result, if you wanted to close the pop-up before it disappeared automatically, you would need to click the ‘x’ multiple times.
• Fixed an issue on the Differential expression view where most entries in the main Biological Insights table would be missing once you had opened the expanded table by clicking the View details button.
• Fixed a bug where Venn diagram labels would contain the text “Fold change”.

 

QIAGEN RNA-seq Analysis Portal 2.0.1

Released December 2021

Improvements and bugfixes

• Improved performance of the Send copy of project functionality for larger projects.
• Fixed an issue with the Send copy of project functionality where case sensitivity on the recipient email address caused the project to not always show up in the recipient’s RNA-seq Analysis Portal account.
• Fixed an issue where Align and count analysis would fail for RNA Stranded data if ‘Spike-ins’ was selected.
• Fixed an issue for the QIAseq miRNA Library Kit Quality control report where the Summary column ‘UMI reads annotated’ listed the values for ‘Total UMI reads’ instead of ‘Total UMI reads annotated’.
• Fixed an issue where coloring on the volcano plot was opposite of what was indicated by the legend.
• Fixed an issue with the Quality control report for RNA sample kits where the Summary column ‘Total rRNA’ would incorrectly show ‘-%’ when Mt_rRNA reads, but no cytoplasmic rRNA reads were detected.

 

QIAGEN RNA-seq Analysis Portal 2.0

• On the project view, the list of experiments is sorted by Created date, newest experiment on top.
• Data upload: Warnings relating to the selected fastq files are presented in a modal dialog to increase visibility, and messaging has been improved.
• In the Align and count dialog, you will get a warning if you are about to produce samples with same name as samples already in the selected project.
• In the Create experiment dialog, the Sample kit vendor, Sample kit, and Reference dropdowns will display only values that apply to the samples in the selected project. When only one value applies, this will be pre-selected.
• Differential expression view
  • You can choose between raw p-value and FDR p-value for filtering and display of the volcano plot.
  • If you apply a functional filter by selecting e.g. a canonical pathway, on the volcano plot items that are not associated with the pathway will be colored differently, leaving green-yellow colors only on the filtered feature subset.
• Samples and Quality report
  • The report will be generated also for experiments where all samples were successfully created, but the subsequent differential expression analysis failed.
  • The use of integers vs. decimal numbers has been improved, and values are now rounded correctly.
  • On the PCA plot you have the choice of turning labels on or off, and the plot scaling was improved.
• For miRNA samples, reference information will include the applied miRBase version.
• Support for copying text and table contents to the clipboard was improved.
• Various minor enhancements to the user interface.

Bugfixes

• Fixed an issue with the Differential expression view where applying a functional filter from the biological insights table would sometimes exclude too many genes from the feature table.
• Fixed an issue with the Comparison view where features with ‘-‘ values across the underlying differential expressions would be included in table and plot.
• Fixed an issue with the Comparison view where the Venn diagram circles would sometimes overlap. This could happen if the attributes applied for the experiment contained hyphens and gave rise to differential expression analyses names that were identical up until the first hyphen.
• Fixed an issue in the Create experiment dialog where the ‘Experimental setup (comparisons)’ dropdown did not allow you to select the enabled options if the attribute selected for ‘Test differential expression due to’ had 8 or more values.
• Fixed an issue in the Create experiment dialog where the ‘Select all’ functionality sometimes did not work as expected.
• Fixed an issue in the Create experiment dialog where experiments would sometimes fail if for the applied metadata the same attribute value was used for more than one attribute.
• Fixed an issue with visualization on the Samples and quality control report where a vertical scroll bar would be added and tables truncated even when not needed.
• Fixed an issue where “Share experiment with Support” would sometimes be enabled by mistake and result in an error if you attempted to use the functionality.
• Fixed an issue where “Share experiment with Support” would fail for large experiments.
