HI, Since the log files and crashed .pdb files had filled the whole disk space I had to delete them and start again. I am simulating a homodimer protein in a water box. I have mutated three residues and want to look the behaviour of the protein. I have four setups for the same protein without mutation and with mutation and respective controls. Among the four only one is crashing at the position restraint stage. The other three didnt show me this error (except for the one line LINCS warning). I have run the position restrained dynamics again. Yes as you are saying it starts with LINCS warning. This is what it says after the LINCS warning. ***************** Back Off! I just backed up step20672.pdb to ./#step20672.pdb.1# Sorry couldn't backup step20672.pdb to ./#step20672.pdb.1# Wrote pdb files with previous and current coordinates Wrote pdb files with previous and current coordinates

I am attaching the .mdp file along with this email.
Thanks in advance.
