Hi, I imported several .STL files into Chimera that I generated using TrakEM2. These import as individual surface objects in Chimera. I am then able to color the objects differently and generate some publication-quality screenshots. However, I am unable to save and restore the Chimera session. Upon trying to restore the session, I am presented with a blank screen. The program does not report any errors and even says "Done opening SESSION.py". It seems that the program never loaded the surface files. How does Chimera know where the surface files are located? I saw no mention of their location inside the session PY file. How can I save my session so that next time I open Chimera, all of my surfaces load with the colors, transparency, etc. that I assigned them in Chimera? -- Arjun Dayal Pritzker School of Medicine | Class of 2016 University of Chicago
