Chimera for Mac

Interactive visualization and analysis of molecular structures and related data.

In English

Chimera overview

UCSF Chimera is a highly extensible program for interactive visualization and analysis of molecular structures and related data, including density maps, supramolecular assemblies, sequence alignments, docking results, trajectories, and conformational ensembles. High-quality images and animations can be generated. Chimera includes complete documentation and several tutorials, and can be downloaded free of charge for academic, government, non-profit, and personal use.

Chimera is developed by the Resource for Biocomputing, Visualization, and Informatics, funded by the National Institutes of Health (NIGMS P41-GM103311).

What’s new in version


Note: Now requires OS X 10.10 or later

General Changes:
  • AmberTools updated to version 18
  • Previous/Next buttons added to activation/display button rows below the command line, for quickly cycling through (or toggling between) model display and/or activation
Tool Changes:
  • Area/Volume from Web (Surface/Binding Analysis) — removed because the NIH StrucTools server is no longer available
  • Multalign Viewer (Sequence) — option to get annotations from the Conserved Domain Database (CDD) removed due to CDD changes
  • MD Movie preserves PSF segment name as residue attribute segment, and reports the segment names to the Reply Log as the trajectory is read. Therefore a segment named XYZ could be referenced in a command using the atom specifier :/segment=XYZ
Notable Bug Fixes:
  • Upgraded Tk windowing toolkit to fix bug on Mac where specifying multiple coordinate files in MD Movie could hang Chimera.
  • Fixed problem at startup with libfontconfig on recent versions of Linux.
  • Fixed problem reading GROMACS trajectories on recent versions of Linux.
Known Bugs:
  • Surfaces fail for some structures
