[gmx-users] g_wham

[Jose Javier Lopez Cascales]

Hi guys,

I am facing some troubles when I am trying to use the code g_wham with
my Gromacs 3.3.

The input of g_wham was as follows:

> g_wham pull.pdo pull_1.pdo ... pull_10.pdo -o cabe.xvg -hist  histo.xvg

Then, the output that I received from g_wham is,

gunzip: stdin: not in gzip format
-------------------------------------------------------
Program g_wham, VERSION 3.3
Source code file: gmx_wham.c, line: 90

Fatal error:
This does not appear to be a valid pdo file
-------------------------------------------------------

Furthermore, we also introduced pull.pdo.gz instead of pull.pdo and
then, we obtained the following message,

Opening file pull.pdo.gz.
-------------------------------------------------------
Program g_wham, VERSION 3.3
Source code file: gmx_wham.c, line: 90

Fatal error:
This does not appear to be a valid pdo file
-------------------------------------------------------


May anyone help me with g_wham?

Thanks a lot in advance for your collaboration,

Regards

Javier Lopez
