• Duplicating a subset of a LiveReport that included a MPO would show an error message if the input columns were not also selected, and now duplicating a subset of a LiveReport does not require selecting input columns to a MPO

LiveDesign

What’s new in LiveDesign 2022-1

• A new compound sketcher has been introduced, which was designed and developed by Schrodinger
• Add a compound to the sketcher by searching for its ID to use it as a basis for future designs
• Gadgets appear in a new location, along the left-hand panel, and can be grouped into categories to facilitate more rapid discovery of the appropriate gadget
• Computational modeling results can be aligned across columns on a per-pose basis, in order to identify related predicted values
• Tooltips can scroll to show long column descriptions when hovering over a column header

What’s been fixed

• MPOs with Freeform column inputs were not editable when copied from one project to another, and now are editable
• Unpublished clustering models showed duplicate values when a LiveReport was copied, and now show a single predicted value
• 3D data uploaded from Maestro would not appear in the Data & Columns tree, if the LiveDesign instance was configured to group experimental assays by concentration, and now will always appear
• Formula columns and Freeform columns could take several minutes to appear in a duplicated LiveReport, and now appear immediately
• The “Publish” button in the column menu of unpublished models would disappear after clicking it, and now will continue to appear
• Protocols that had a parameter set to optional could not have the parameter changed to mandatory, and now permit setting the parameter to mandatory
• LiveReport tabs could not be dragged and rearranged, and now can be dragged and rearranged
• Protocols that were made accessible in a project, and then made inaccessible to that project, would hide all models based on that protocol. The models now continue to appear in the Admin Panel
• Parameterized models would not display the column name in the Admin Panel when a Freeform column was used as the input parameter, and now display the column name
• Asynchronous tasks that took longer than the timeout period of eight days to complete were not canceled, and now are automatically canceled after eight days
• Creating models with optional parameters has an improved user interface
