Hi Jianhao, Just delete the residues you don't want. E.g. if the residues are numbered 1-1000 and you don't want 501-1000, then command: delete :501-1000.a ... of course, you can use any command-line atom specification, e.g. selecting that part and then delete sel <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/delete.html> <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html> If you wanted it as a file, then just save a PDB file after you do the deletion. E.g. menu File... Save PDB, or command "write": <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/savemodel.html#pdb> <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/write.html> I hope this helps, Elaine ----- Elaine C.

Hi, I have a pdb with a A chain of 1000 amino acids. How can I make a new model with a part of A chain (i.e. 500 amino acids) using command line? Thank you!
Best, Jianhao
