Hi All,
I have some problems with g_wham, and i already gone through all the
postings and didn't find a hint..
For problems like these (which are hard to diagnose!), your Gromacs version,
compilers used, OS, etc. would be useful.
basically, I'm trying to calculate PMF between two charged plates. I've
performed a pulling simulation between the 2 plates according to
Justin's UMBRELLA tutorial in the website (all steps, i.e.,
minimization, equilibration etc. up to that point work fine)
from the pulling i generated input configurations for the umbrella
sampling runs (pull=umbrella , rate=0.0), which are 15 ns long
and collected all the output pullf.xvg and *.tpr files.
i then run g_wham (with -it and -if) and it works fine at the beginning,
A real command line would be better. Does g_wham report reading in all of the
files correctly?
but then the computer simply gets stuck (!?) and the calculation is
killed - with no error massage.
what is it that I'm doing wrong?
Not a clue, based on what you've provided. Sounds like a reasonable procedure
to me.
it looks like my output data (pullf and tpr files) are fine, but is it
possible that some of them causing the problem?
Are your input files (.dat) intact? In the appropriate order, etc? Are all
your file names unique? Additional details like these would be good. You can
also add the -debug flag to get a .log file of what g_wham is doing. That might
be useful.

this is really frustrating..
need your help,
Amir
