Dear users,
I ran a WHAM analysis after umbrella sampling simulation, and this error
occurred:
Reading pull force file with pull geometry distance and 1 pull dimensions
Expecting these columns in pull file:
0 reference columns for each individual pull coordinate
1 data columns for each pull coordinate
With 1 pull groups, expect 2 columns (including the time column)

Program gmx wham, VERSION 5.1.4-dev
Source code file:
/home/biotech/Downloads/gromacs-5.1.4/src/gromacs/gmxana/gmx_wham.cpp, line:
2240
Fatal error:
Empty pull force file npt12_pullf.xvg
Why is the pull force file not generated for the particular xvg file? If the
file is empty, then how should I fix it? Should I redo the umbrella sampling
simulation?
With thanks and regards,
