[Chimera-users] Query: Saved pdb doesnt have mutated residue

Respected Chimera team! I have a pdb file in which i have done mutation by using swapaa command in IDLE python but once i saved the structure then new saved structure doesn't have mutated residues in it. commands: 1.rc("open filename.pdb") 2.rc("swapaa val #0:2.a") 3.new_file_name="val.pdb" 4.rc("write format pdb #0 C:\\Users\\folder" + new_file_name) 5.rc("save newsession") 6.rc("close session") 7.rc("close all")
