[gmx-users] Help with eneconv

[Alexandre Suman de Araujo]

My problema is not with de time values on .xvg output files.
My problem is that I need to run a program I made that depends of the
time values from .edr file.
I thought that such thing would be easy to do in eneconv, but now I´m
seeing that its not so easy.

Thanks
