Thomas, thanks for help!
As I understood fconv can be used for the split several mol2 (or pdb) files
which was placed in 1 model to the several pdb files, doesnt it ?
In past I forced with some problems with g_hbond. Is there any other way
to monitor h bonds along the trajectory (e.g in vmd) ?
PoseView is used as the separate software or web server
http://poseview.zbh.uni-hamburg.de/poseview ( I mean that I analyze polar
interactions both in pymol as well as via pose view).
