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")
