[gmx-users] question about pdb file

[delara aghaie]

Dear Gromacs users
I have encountered in pdb data bank with Human interferon crystal structure:
PDB ID : 1ITF
http://www.rcsb.org/pdb/explore/explore.do?structureId=1ITF

It is mentioned that it contains 24 structures. I opened the file and saw there are 24 models there.

Now if I want to do some simulations on this protein, how should I know which model to select and when doing pdb2gmx, I should delete the other models?

Thanks
Regards
D.M
