Hi Amith,
If it was just one file, I would probably just text-edit the residue name in the PDB file before opening it.

However, if you would rather avoid text-editing the file or you need to process a large number of files, you can do it in ChimeraX with a "setattr" command.  For example, to rename all residues named UNK to LIG instead:

setattr :UNK residues name LIG

See <https://rbvi.ucsf.edu/chimerax/docs/user/commands/setattr.html>

I hope this helps,
Elaine
