Dear Jason;

Say I extract the trajectory with frames below RMSD 1 Ang. from the
reference structure using this

trajin *md1.mdcrd*
rms R1 first :1-198 .CA
outtraj frames_rms1_md1.mdcrd maxmin R1 min 0.0 max 1.0

Say now I have frames_rms1_md1.mdcrd. How can I process this
frames_rms1_md1.mdcrd file for MMGBSA/MMPBSA and how can I define frames in
this case. Also frames_rms1_md1.mdcrd contins trimmed trajectories within
RMSD 1 Ang.. So if I want to process this trajectory how can I process it
for mmpbsa or gbsa. How an input file will look like in this case.

Thank you so much for all your time and help.
