NAME

       g_wham - weighted histogram analysis after umbrella sampling

       VERSION 4.0.1

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
