DesertSci is please to provide a short summary of the latest enhancements in the first release of Proasis4, 2021:

–  When a search returns more than 1000 hits, a pop-up is provided asking if one wants to load all, then cancel or continue as required

–  New Overlay method: “Antibody alignment, residues 1-100”

–  In Global Settings, there is a new button in section ‘Rendering’:
o  Show Organic as sticks
(show all HETs as sticks)

–  In ‘Structure Details’, there are new buttons at the top of the selection panel:
o Expand All       o Show All
o Collapse All     o Hide All

–  There are Viper GUI extensions, with new online tutorials

–  There are Felix GUI extensions, with new online tutorials

–  Potential unfavourable torsion angles are now highlighted for bound ligands, shown as Property torsion_flags (red atoms indicate the possibility of an unfavourable torsion and orange means borderline)

–  Filtering on search results now updates hit list numbers, and additionally, enable subsets of filtered hits to be more-easily explored using the Report tools

–  Filtering on search results now with NOT logic now included (as !MyProject, for example) following a Ligand Similarity Text search starting with a strucid from MyProject

–  Protein cartoon colouring is now done to match carbon atom colouring for each chain
