Hi Jonas, I added an initial color zone command to ChimeraX, will be in tonight’s daily build. Here’s an example, image attached. open 5199 from emdb open 4v7q color #1 zone #2 dist 10 And a few more commands to lower the contour level, increase to full resolution (step 1), and hide the connected bits of density less than 1 nm in size: vol #1 level .1 step 1 surf dust #1 size 10 color #1 zone #2 dist 10 This color zone doesn’t automatically recolor yet when the surface changes (e.g. new contour level). Needs some more work. Tom

Hi Jonas,

The color zone capability is not yet in ChimeraX. I’ll see if I can add that later this week.

Dear chimeraX users/developers

Is there an easy way to color a cryoem density map based on individual subunits (from a pdb file) - similar to the color zone functionality in chimera?

Thanks a lot

Best Jonas
