Hello,
I am using g_sham to plot a one dimensional free energy profile for a
given reaction coordinate( in my case it is first principal
component(PC1) from a principal component analysis). It gives me the bin
index Vs free energy plot, but I want PC's value
Vs free energy plot. Please suggest me whether it is possible through
g_sham or not.
Doubtful. g_sham creates free energy surfaces, which are inherently 2D. I
don't think you can get it to calculate the free energy of a given PC value,
although from the free energy vs. bin plot you can probably determine something
close. The bindex.ndx file should contain some information that can be used to
translate the bin to the values contained within, since it's all derived from a
histogram.
