Hii;
Please attach pdbs corresponding to 2s, 5s, 6s, 7s, 10s, 21s, and 22s using
CPPTRAJ outtraj command. Attach those pdbs. Then we can see.
Command for dumping PDB
trajin md2.mdcrd
autoimage
strip :WAT,Na+ outprefix stripped
outtraj snapshot.pdb onlyframes 30000 (put 2000 for 2ns, 5000 for 5ns, 6000
for 6ns here)
trajout md2_dry.mdcrd
