[gmx-users] g_ hbond on two peptides
Hi, I use g_hbond to analyze the system with two peptide. And I introduce the ndx file which include two group for the two peptides respectively. For the first prompt of g_hbond, I choose the group of the first peptide. For the second prompt, I choose the other peptide. I got the data that announced 4 H-bonds were found. And then I use rasmol to check, I found there are 2 intra-H-bonds in first peptide and 2 intra-H-bonds in the second. There are no inter-H-bonds between two peptides in my system. It's strange since I had selected different group to analyze when g_hbond promted. How should I do to exclude the intra-H-bond on one peptide?

Have you looked into which hbonds are found? And are you sure your index file is error free? /Erik -- --- Erik Marklund, PhD student Dept. of Cell and Molecular Biology, Uppsala University.

You may also want to check that both programs define H-bond in the same manner. /Erik -- --- Erik Marklund, PhD student Dept. of Cell and Molecular Biology, Uppsala University.
