Hi Tianming, You didn't say what your coloring means: whether it is color by distance or some property. However, you can get parts of a map by various different methods: (1) volume zone (hide some parts by some distance from some atoms) <https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#zone> (2) interactively using the Map Eraser tool to set some parts to zero <https://rbvi.ucsf.edu/chimerax/docs/user/tools/maperaser.html> <https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#erase> (2) interactively cropping the map box, e.g. in Volume Viewer choosing display style "box" and using the mouse to "crop volume" <https://rbvi.ucsf.edu/chimerax/docs/user/tools/volumeviewer.html> I prefer to avoid zooming -- there are so many users and so many questions it would be too many meetings!

Dear ChimeraX group,
My name is Tianming Qu and I am currently a phd candidate in Florida State University working on MD simulation study about enzyme proteins. I am currently trying to use chimeraX to show a water density map calculated from an MD trajectory and I got the following fig as result: <image001.png>
I wonder if the ChimeraX can grab the “red region”out of the whole map, since this the “pocket region”I want.
Looking forward to your reply! And it will be my great pleasure if I can have a chance to talk (maybe zoom?) to one of the developers in ChimeraX group! Thanks a lot for the help.
Best, Tianming
