You can save a copy of the original and then superimpose the copy back onto it
# using "fab" command from the latest 1.2 beta to create poly-ala
fab  AAAAAAA, pol
# create copy of the polymer
create copy, pol
# adjust a torsion
set_dihedral pol///4/N, pol///4/CA, pol///4/C, pol///5/N, 60
# superimpose back on the original copy
fit pol, copy

Subject: [PyMOL] reorienting a chain


I have a long chain of polymer. Once I change some dihedral angles, it
orients in a different direction. I would like the chain to be
reoriented in the same direction as it initially was. Is it possible
within pymol ? How can I achieve this ?

Thank you and Regards,
