Sir,
Is there any need to do a "mass weighted backbone RMS fit of every frame to
the first frame in the trajectory" before performing hbond analysis(by
ptraj). Also on analysing solvent interaction with the system ( dsDNA). is
it sufficient to reimage like (used iwrap=1)
center :1-20 mass origin// dna
image origin center familiar
center :1-38 mass origin //Na ions
image origin center familiar
center :1-5529 mass origin// water residue
image origin center familiar
Also if i have to strip water residues at a distance greater than 3.6
angstrom;
would it be ok to have all these in a single script.
I dont want to create another prmtop.
Hbond would be performed on the reimaged trajectory. Isnt?
Thanking you
Mary Varughese
