[gmx-users] AWH with two bias potentials

[Berk Hess]

I see now that you used awh-nbias=2 with awh-ndim=1. Thus you asked for 2 independent 1D AWH  biases and PMFs. You might be able to get a 2D PMF from that, but that is complicated.
I think that what you want is one 2D bias: awh-nbias=1 with awh-ndim=2.

Dear Berk,

I do get a set of PMF files at different times for each reaction
coordinate from gmx awh. Each file has two columns (x=coordinate 1,
y=PMF or x=coordinate 2, y=PMF). My coding and maths skills are quite
limited so if you have a script that can convert these data to a 2D
format, I would be happy to use it.

The 1D nature of xvg files is not convenient for visualization though, so you need to write a script to convert it to you favorite 2D data format. I probably have a script somewhere for some 2D format (python?) if you can't write it yourself.
