RMSD_perres according to previous frame as ref

[dafwb]

Hi,
I want to calculate the RMSD of one residue with previous frame as reference. My idea was to use the rmsd_perres() with ref='previous', but this doesn't work. Other option would to call the function via a for-loop, but i am wondering, if there is a more efficient option.
best regards,
Daniel

hi @dafwb, that feature is not supported (since there's no request for cpptraj previously I guess).

cc @drroe since it's more about cpptraj.

cpptraj already has it but pytraj does not support it yet.

Just to clarify, this can be done via cpptraj using the previous keyword for the rmsd command (in conjunction with the perres etc keywords).
