Hi Andy,
I've just checked the amber7, amber8, and amber9
versions of ptraj manuals. You were right when you
said that it calculates both the parameters but... I
still have doubts. I mean, amber9-ptraj really
calculates RMSD and Radius of Gyration. Nevertheless,
apparently, amber8-ptraj and amber7-ptraj are only
able to calculate RMSD.
We usually work with amber7, and I was wondering... Is
it really true that amber7 and amber8 versions of
ptraj cannot calculate radius of gyration? Or maybe it
was ommited in the manual but still they were able to
do that?
Any help??? I'm really interested, because we work
with amber7!!!
Thank you very much in advance...
