Hi rosajaan,
I had the same problem last week (at least so I
think). I needed to calculate the radius of giration
and the RMSD for some molecules. I intended to do it
with ptraj but the option was not available. I was
told to use CARNAL, and after fighting hard with it, I
managed to run the calculation.
Try to customize the files attached to this e-mail to
your needs. You will probably need to adjust some
lines to define your atoms/residues/ etc: Try to check
AMBER 7 manual, page 219, to the bottom (DECLARE
paragraf).
If you need to previously remove water solvent from
the box, its better you to use ptraj (I find it really
easier than CARNAL).
I know, handling CARNAL is a big nightmare, but I
don't know wether exists another possibility. We will
have to wait until some brave programmer decides to
include these useful options into ptraj.
Good Luck!!!
