[Chimera-users] Chimera ac Im command not working

Dear Chimera team, I am using Chimera to view the surface pane of my TEM images in attempts to see the features of the image in 3D. Since I stained it positively, I have to invert the map values so I can properly view it under “surface”. However, when I do so in Chimera 1.5, it displays an “unexpected python error”. When tried in Chimera 1.6, the result is simply a black screen. I am stumped as to how to solve this issue. A colleague of mine done it and I followed the same procedure he has done, but to no avail. Best, Wayne
