Dear gmx users,
I'm fairly new to gmx and I'm using the analysis tools to understand the
persistent features of a large ensemble of conformers of an unstructured
protein restrained with PRE NMR data.
I generated a contact map over the ensemble using the following command
g_mdmat -f fname.pdb -s fname.pdb -mean
Viewing the map after converting with xpm2ps, I found a few persistent contacts.
I then tried to look at the minimum distance distribution for the residue pairs
that gave the closest contacts in the average contact map.
I used make_ndx to create selections of all atoms of the residues of interest,
then used the g_mindist with a pair of residues selected.
g_mindist -f fname.pdb -s fname.pdb -n myindexfile.ndx
If I average over the output of g_mindist, I do not get a value that is near
the discrete value in the g_mdmat contact map representation. Should these
values be the same? If not, why not?
Thanks,
David Lowry
