Hi,
I believe you can get the output you want using the cpptraj
'nativecontacts' command, something like:
nativecontacts name NC2 :10-14.CA :17-21.CA out nc.hp2.ca.dat \
mindist maxdist writecontacts nc2.contacts.dat \
resout nc2.res.dat
In this example I'm using two masks to restrict the search to contacts
between two regions, but you can also use just 1 mask. See the manual
for further details. Hope this helps,
-Dan
