What’s New in 2025-2

• Import Antibody-Drug Conjugates from SimpleSchema
• Freeform Columns
  • New “Comment” type: Write threaded conversations within a Freeform column, and track usernames and timestamps
  • Creating a Freeform column is now performed using a wizard that permits selecting the data type of the Freeform column first, and then specifying the Freeform column details
• Formulas
  • Formulas support multiple values: Input cells to formulas can now contain multiple valuesFormulas can output multiple values, aligned by Experiment, Lot, or Pose. New formula functions were created to handle input cells with multiple values: cellAggregation(), join(), any(), and all()
  • Failed model cells can now be used as formula input
  • A new isFailed() function returns true for any failed model cells, and false otherwise
• Dashboards (Previously called Landing Pages)
  • Biologics and Generic entities are now supported on Landing Pages
  • Project Admins can edit the project description directly on Landing pages instead of configuring it from the Admin panel
  • Project admins can now select a date range via the ‘Time range’ filter in Landing Page Entities Section to look for entities added within a range of days
  • A ‘Bookmark LiveReport…’ option has been added in the LR grid menu and clicking on the option redirects the user directly to the new Bookmark page (in Landing pages) in a new window. The LiveReport’s name gets auto-populated in the LiveReport info section of the window
• Admin Panel: Add multiple new users at once with a CSV upload
• Sequence Viewer
  • Perform sequence-activity relationship analyses by viewing multiple data columns in the sequence viewer
  • Select a reference sequence even when there’s no alignment
  • Retry failed alignments and cancel running alignments
• Unification of Generic Entity and Biologics Import Pipeline: Generic Entity and Biologics import tabs are collapsed into “Biologics/Others” tab. All entities imported from “Biologics/Others” tab are virtual entities. Allows csv import of metadata on virtual entities.
• UX Improvements
  • Users now have the quick filter options to filter by any/all types of Entities on Advanced search, just like in the Filter panel. They can choose from the options of All, Compound, R-group, Biologic and GE
  • Users can now drag a compound structure to Advanced search to create a new substructure query, like in Filter panel
  • Export data qualifiers (e.g., the greater than symbol ‘>’) as a separate column in data exports
  • Exporting a LiveReport: Choose whether to include filtered out rows, or exclude them, when exporting via the User Interface or LDClient
• Structure Processor: A new “STRICT” processor setting allows compounds with valence violations and other invalid chemistries to be accepted or rejected by the processor. By default, compounds with valence violations are not permitted

What’s Been Fixed

• Data and Columns Tree
  • Attempting to favorite published Limited Assay Columns in the Data & Columns Tree would fail, and now those columns can be favorited
• Filters
  • LiveReport filters in Complex view would show additional brackets to the filter conditions, and the filter conditions would rearrange, when columns were removed from LiveReports. The arrangement of filter conditions are now properly retained and brackets do not appear
  • Removing a column from a LiveReport while viewing the Filter panel would change the Filters view from simple mode to complex mode, and now keep the view in simple mode
  • Filtering out a frozen row would show flashing squares in the first row in the main spreadsheet, and now correctly shows that row’s data
• Forms
  • Copying text from a Forms widget previously showed dotted lines in multiple widgets, and incorrectly indicated that text from multiple widgets was copied. Dotted lines now appear only around the cells within a single widget that were most recently selected
  • Forms annotation widgets would not persist styling changes (e.g., font color), and now correctly persist the changes
  • Matrix widgets included excess whitespace around values; the minimum row height has been reduced to eliminate excess whitespace
  • Viewer users could not see 3D results in the 3D Visualizer nor in Forms, and now can view 3D results
• LiveReport Management
  • LiveReport tabs would disappear after logging out and logging in, and now correctly appear after logging back in
  • Clicking a LiveDesign hyperlink would fail to open the linked LiveReport, and instead would open the user’s last-opened LiveReport; clicking hyperlinks now correctly opens the linked LiveReport
  • The Create New LiveReport dialog now permits filtering the list of LiveReport templates
  • Attempting to apply a template to a LiveReport that contained filters would fail, and now applying a template succeeds
  • Overwriting a template would create a new template, instead of overwriting, and now correctly overwrites the template
  • Applying a template to a LiveReport would not include Limited Assay Columns contained within the template, and now correctly include Limited Assay Columns
  • Duplicating a LiveReport would not include all columns by default, and now includes all columns by default
• Maestro Upload
  • Importing structures into Maestro from LiveDesign would occasionally fail when task status of “FINISHED” was reported before the result URL was available, and now correctly imports structures
  • Importing structures into Maestro from LiveDesign would fail if a LiveDesign model returned an empty protein file, and now the empty protein file will be skipped and not imported into Maestro
• Model Creation
  • Configuring a Protocol in the Admin Panel to use a ${RDKIT-MOL} macro would prevent the creation of a parameterized model in the LiveDesign UI, and now correctly allows creating a parameterized model
• Plots
  • Plot tooltips could not be dragged and moved after pinning to the screen, and now can be dragged to a new position after pinning
• R-group Decomposition
  • Reordering R-group Decomposition scaffolds would eliminate coloring rules and sorting rules for R-group columns, and now correctly maintains coloring rules and sorting rules
• Search
  • Advanced Search would occasionally return extra entities that didn’t match the search conditions on columns, when those columns had an undetermined data type, and now does not return extra entities
• Sequence Viewer
  • Horizontally scrolling the sequence viewer would reset the ruler, and show the wrong residue numbers at the top, and now shows the correct residue numbers
• User Administration
  • User email addresses would not save in LiveDesign when using Single Sign-on, and LiveReport notifications would not be emailed to users. Email addresses and are now correctly saved
  • Welcome emails for new users would include an incorrect LiveDesign URL, and now include the correct URL
