• Fixed an issue where one could not zoom in after zooming out fully on very large workflows.ing out fully on very large workflows.
• Fixed an issue that prevented a root folder on Windows drives from being used as a File Location.
• Fixed an issue where updating an existing installation on Windows would result in the .vmoptions file being deleted, which makes the Workbench run with the default Java configuration.

Bug fixes

• When doing manual mutations of protein residues in the 3D view, the new modeled side chain is now again aware of other atoms in the same chain.
• Added a work around to a java issue that occasionally resulted in the Workbench displaying an uninformative error and requiring a restart to continue working.
• Fixed an issue with running BLAST searches at the NCBI where an NCBI-generated error about their CPU usage limit being exceeded was not being reported transparently and a result of “no hits” was being reported instead.
• A fix was applied to avoid an exception in circumstances when the cleanup of downloaded files from BLAST failed.
• Fixed wrong display of “Supported format” when exporting elements from either the Folder Editor or the Local Search Editor.

• Structure alignment improvements. When aligning structures from multiple Molecule Projects, an initial visualization is prepared where all molecules coming from the same Molecule Project will be visualized in the same color. Also, a combined sequence alignment can now be generated which is linked to the 3D view.
• BLAST. BLAST has been upgraded to BLAST+ 2.2.30 that includes a number of improvements and bug fixes. A full list of BLAST+ 2.2.30 changes can be viewed at http://www.ncbi.nlm.nih.gov/books/NBK131777.

• PDB importer. When importing non-standard PDB files without version information, issues were raised for missing element types, even though element types should not be expected.
• PDB importer. When merging ligands with intermolecular bonds, intermolecular bonds to other molecules (such as proteins or cofactors) could be lost.
• PDB importer. Carbamoyl groups were not protonated correctly.
• Molecule file importers. Dialogs would incorrectly accept multiple files for input, even though only the first was imported.
• Ligand optimizer. Changing R/S stereochemistry for atoms in rings with a lone pair position was not possible.
• PDB exporter. If small molecules and protein chains share the same chain ID, this relation is preserved, also if the chain ID is renamed due to name clashes during export.
• 3D viewer. For Molecule Projects with a saved Binding Site Setup and with hydrogen bonds visualized, an exception would be shown when modifying the protonation of an amino acid in the binding site.
• 3D viewer. In rare cases, rendering would fail for Nucleic Acids containing nucleotides of unknown type with no nitrogens.
• General. On OS X, a left-click quickly followed by right-click was interpreted as double-click in some places of the user interface.

  • In the execution wizard of a workflow the “Reset to default” button is now active.
  • All icons in the workflow editor are now on the left side.
  • Introduction of snippets: Parts of workflows can now be saved as a snippet and reused in other workflows.

  • The workflow editor can now open workflows in which the graphical view of the workflow is corrupt.
  • Fixed an exception which could occur during workflow migration.
  • Data with the same name can now be bundled multiple times in a workflow installer.
  • Previously when a plugin contained custom actions and a workflow, the workflow could not be installed. This has been fixed.
  • Fixed problem with unlocked output names that previously could not be configured during execution of a workflow.
  • A workflow with configured data from a server is now automatically validated when connected to the server (when opened in the editor). Previously the workflow had to be closed and reopened first.
  • The original workflow file included in a workflow installer can now be exported directly without having to restart the workbench in advance.

• A problem with saved table settings that sometimes did not work has been fixed. The bug fix includes a more robust/generic way of saving table settings with different columns. To fix this problem, existing saved table settings should first be loaded on an object where it works (i.e. has the same columns as when it was saved); and then the table settings should be saved with the old name to overwrite the settings.

• Fixed an error that could cause batch processing to open all results rather than saving them.

• Metadata for phylogenetic trees: A bug has been fixed with import of metadata containing column names with colons.
• Fixed error when showing protein translations of annotations shorter than 3 bases.
• Two problems with the F1 help has been fixed; 1) When pressing F1 in a workflow tool wizard more than one help window appeared, and 2) Fixed problems showing help by pressing the F1 key in tool wizards.

• Protein Structure Alignment – high quality structural alignment of whole protein chains or selected regions of a protein.
• Calculate Molecular Properties – small molecule descriptors, including a XlogP implementation.
