[Chimera-users] Question regarding rotating dihedrals

[Rodrigo Galindo-Murillo]

Hello!

I need to do a dihedral scan around the phi/psi angles of alanine
dipeptide and to create the input files to later do single point
calculations I am using the cmd script:

open ../scan.pdb
rotation 0 @/serialNumber=7 @/serialNumber=9
rotation 0 180
write format pdb #0 test.pdb

I need to use atom serial numbers since the idea is later do the scan
with non-canonical peptides that will not work with the native phi/psi
descriptions.

The script is not modifying any angle but I can see that is generating
test.pdb correctly.  Could you please orient me if this is the correct
set of instructions?

Thank you!

Rodrigo.
