Description

Compute partial densities across the box, using an index file. Densities in gram/cubic centimeter, number densities or electron densities can be calculated. For electron densities, each atom is weighed by its atomic partial charge.

Files

-f traj.xtc Input Generic trajectory: xtc trr trj gro g96 pdb
-n index.ndx Input, Opt. Index file
-s topol.tpr Input Generic run input: tpr tpb tpa
-ei electrons.dat Output Generic data file

Other options

optiontypedefaultdescription
-[no]h bool no Print help info and quit
-[no]X bool no Use dialog box GUI to edit command line options
-nice int 19 Set the nicelevel
-b time -1 First frame (ps) to read from trajectory
-e time -1 Last frame (ps) to read from trajectory
-dt time -1 Only use frame when t MOD dt = first time (ps)
-[no]w bool no View output xvg, xpm, eps and pdb files
-d string Z Take the normal on the membrane in direction X, Y or Z.
-sl int 10 Divide the box in #nr slices.
-[no]number bool no Calculate number density instead of mass density. Hydrogens are not counted!
-[no]ed bool no Calculate electron density instead of mass density
-[no]count bool no Only count atoms in slices, no densities. Hydrogens are not counted
