Colton, I think you're looking for the sample and map keywords of the color command. I'm not sure if there's a tool for doing this like the Surface Color tool in Chimera. https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#sample For example, I've got an electron isodensity surface in model #1 and the ESP in model #2. I can color the electron density based on the ESP with `color sample #1 map #2 palette -0.024,red:-0.012,yellow:0,green:0.012,cyan:0.024,blue` This will color #1 rainbow colors based on the ESP values between -0.024 to 0.024 from #2. The custom palette specification is the thresholds levels and colors separated by commas, with each of those separated by colons. https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#palette I used color names, but there are several other ways to specify colors: https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/colornames.html Best, Tony ________________________________ From: ChimeraX-users <chimerax-users-bounces@cgl.ucsf.edu> on behalf of Colton Carlson <cdc01@chem.ubc.ca> Sent: Tuesday, March 9, 2021 12:39 PM To: chimerax-users@cgl.ucsf.edu <chimerax-users@cgl.ucsf.edu> Subject: [chimerax-users] Volumes [EXTERNAL SENDER - PROCEED CAUTIOUSLY] Hello, I am just wondering if ChimeraX has added the ability to colour surfaces based on the values of a different surface? That is, input 2 cube files, then colour one cube file based on the values of the other. It is available in the other version of chimera, but the only information I could find on this was from 2018 and said it was not yet implemented in ChimeraX. Thanks a bunch!
