Dear Amber users
I am interested in computing the radial density distribution of my
macromolecule.
I used ptraj for this. I have got 3 .xmgr files generated: volume, standard and
carnal.
I looked up in the manual amber9, and in the mailing list but I cannot find the
meaning of the 3 columns in each file. I am interested in plotting the radial
density distribution of water HOH inside my macromolecule versus R.
I want to use the center of mass of the macromolecule as the reference. I
performed explicit solvent MD.
My input looks like this:
trajin pdb_bond_wat_md1_exp.mdcrd
trajin pdb_bond_wat_md2_exp.mdcrd
center :1-121 mass origin
image origin center familiar
radial pdb_bond_wat_rad_dens.rdf 0.5 40.0 :HOH_at_O:1-121 closest
I want to do this averaged over 200 ps.
Any help or comments on this are very welcome
Best,
