[PyMOL] mutagenesis

[Nalam, Madhavi]

Hello:
I am trying to mutate ALA to VAL in PyMOL. I would like to see possible
rotamers for Val. Is it possible to do this in PyMOL?
I am using mutagenesis option in PyMOL. Once I select the Val residue,
it asks to select a conformational state. I assume this is for various
rotamers. But how do I choose a conformational state?
Thanks in advance,
Madhavi
