Dear Amber users,

I'm trying to make tpp and xyz file of a crystal cell of phenylalanines. First, I generated mol2 file with antechamber and when trying to run parmchk I got message: "segmentation fault". When I tried to run directly tleap the same error appears after syntax "phe = loadmol2 file.mol2". Error message is as fallows:

I was running many times different jobs on my system and there was no problem. One difference is that now I have pdb and mol2 with 380 Phenylalanines not connected (from crystal structure) (previously I was always using one ligand and protein). I'm using Amber10 with Amber tools 1.3.

Take a look at my mol2 file if necessary (attached)
Please, help with this.

Thanks in advance.
