[Chimera-users] identifying and counting selected residues

[Smit Patel]

respected ma'am

greetings for the day!

Sorry to disturb you again. can you pls tell me the process to run this
selection inspector tool using chimera --nogui option. I tried but couldn't
find any. Also in the python 2.7 scripts, the inspect.py script is hard to
understand. Can you pls tell me to count residues without any involvement
of GUI? it would be really helpful.

thank you,
Regards
