[Chimera-users] Command line syntax questions

[Elaine Meng]

Hi Divita,
You are welcome to try it, but I don’t think that approach will work.  That is, it will not let you combine without renumbering or changing chain ID when both input models already have the same residue number with same chain ID.  I believe I even tried that yesterday to confirm it didn’t work.
Best,
Elaine
