NAME

g_wham - weighted histogram analysis after umbrella sampling

SYNOPSIS

g_wham -o profile.xvg -hist histo.xvg -[no]h -nice int -[no]w -[no]xvgr -min real -max real -bins int -[no]prof -temp real -[no]flip -tol real

DESCRIPTION

This is an analysis program that implements the Weighted Histogram Analysis Method (WHAM). It is intended to analyze .pdo files generated by mdrun using umbrella sampling tocreate a potential of mean force (PMF). The options are


   -o
     name of the PMF output file


   -hist
  name of the histograms output file


   -min
   minimum coordinate to use


   -max
   maximum coordinate to use

Note: the program will throw out any data that is outside of min - max. The program will output the true min and max after completion, so you can use these values the next time. or you can use:


   -noprof only calculate min and max


   -bins
  number of bins to use in calculation

FILES

-o profile.xvg Output
 xvgr/xmgr file 

-hist histo.xvg Output
