DESCRIPTION
gmx rmsf computes the root mean square fluctuation (RMSF, i.e. standard deviation) of atomic positions in the trajectory (supplied with -f ) after (optionally) fitting to a reference frame (supplied with -s ).
With option -oq the RMSF values are converted to B-factor values, which are written to a .pdb file. By default, the coordinates in this output file are taken from the structure file provided with -s ,although you can also use coordinates read from a different .pdb fileprovided with -q . There is very little error checking, so in this caseit is your responsibility to make sure all atoms in the structure fileand .pdb file correspond exactly to each other.
Option -ox writes the B-factors to a file with the average coordinates in the trajectory.
With the option -od the root mean square deviation with respect to the reference structure is calculated.
With the option -aniso , gmx rmsf will compute anisotropic temperature factors and then it will also output average coordinates and a .pdb file with ANISOU records (corresponding to the -oq or -ox option). Please note that the U values are orientation-dependent, so before comparison with experimental data you should verify that you fit to the experimental coordinates.
When a .pdb input file is passed to the program and the -aniso flag is set a correlation plot of the Uij will be created, if any anisotropic temperature factors are present in the .pdb file.
With option -dir the average MSF (3x3) matrix is diagonalized. This shows the directions in which the atoms fluctuate the most and the least.
OPTIONS

Structure+mass(db): tpr gro g96 pdb brk ent
-n [<.ndx>] (index.ndx) (Optional)
Index file
-q [<.pdb>] (eiwit.pdb) (Optional)
Protein data bank file
Options to
specify output files:
-oq [<.pdb>] (bfac.pdb) (Optional)
Protein data bank file
-ox [<.pdb>] (xaver.pdb) (Optional)
Protein data bank file
-o [<.xvg>] (rmsf.xvg)
xvgr/xmgr file
-od [<.xvg>] (rmsdev.xvg) (Optional)
xvgr/xmgr file
-oc [<.xvg>] (correl.xvg) (Optional)
xvgr/xmgr file
-dir [<.log>] (rmsf.log) (Optional)
Log file
Other options:
-b <time> (0)
Time of first frame to read from trajectory (default unit ps)
-e <time> (0)
Time of last frame to read from trajectory (default unit ps)
-dt <time> (0)
Only use frame when t MOD dt = first time (default unit ps)
-[no]w (no)
View output .xvg , .xpm , .eps and .pdb files
-xvg <enum> (xmgrace)
xvg plot formatting: xmgrace, xmgr, none
-[no]res (no)
Calculate averages for each residue
-[no]aniso (no)
Compute anisotropic temperature factors
-[no]fit (yes)
Do a least squares superposition before computing RMSF. Without this you must make sure that the reference structure and the trajectory match.
