Hello,
with just
strip !.CA
Ptraj works without any error. But when i make a pdb from the stripped
trajectory, Ptraj shows the other atoms also in the pdb file. Do i need to
create another prmtop consisting of only CA information to work with the
trajectory of only CA atoms. I do not know if it is possible to create such
a prmtop file for just the CA atoms. Is there any way to do the same ?
