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).
--I want to examine protein-ligand interactions observed in the md trajectory using Pymol.
For such task I have 100 snapshots of the protein-ligand complex which I've loaded into the pymol. Now I want to extract from all snapshots 100 ligands as the separate 100 objects and save it in the mol2. Actually I can do such task in the simplest way extracting all ligands in one object but I need as a result 100 mol2 files. Could someone show me example of some script which could do such tasks?
Save all ligands in a multi-mol mol2 file and then split if with fconv -s.
Also I'll be very thankful if someone can provide me with some tool which can be used for investigation of the ligand dynamics along MD trajectory ( in particular I want to visualize all binding poses and define all polar contacts along trajectory). For such task I've being used pymol as well as pose view loading snapshots to that programs but that way is not appropriate for analyzing of the ensembles of the binding poses obtained from md run.
I usually monitor H-bonds with g_hbond from GROMACS Tools and Salt-Bridges with the respective VMD plugin. Then I make a table with frequences of each polar interaction, pick up a frame that contains as many important interactions as possible, load it in PyMOL and draw dotted lines between the interacting atoms.
PS: I didn't know about PoseView plugin, it seems to be a very useful addition to PyMOL :)Thomas
