Dear Sir/ma'am

I have one system Alpha-cyclodextrin with peptide. I want to study
host-guest interaction.
for this study, I am following the paper.
https://pubs.acs.org/doi/pdf/10.1021/jp3128324

Whenever I performing the Adaptive biasing force method I am getting the
following type of graph for Pmf(Kcal/mol) vs zeta.

[image: image.png]
I have chosen the heavy atoms of the peptide whose inside the
alpha-cyclodextrin as the main atoms and second atoms are oxygen
atoms present in the glycosidic bond.
I have also query ho to choose lowerboundary and upperboundary.

I have also attached the colvar file.
Kindly give me some suggestions to understand this issue.

Best Regards

Aashish
