Sir, I am doing membrane protein dynamics in lipid bilayer, using oplsaa force field. When I am doing minimization after genion I getting message like this Back Off! I just backed up ions_1.tpr.trr to ./#ions_1.tpr.trr.2#
ack Off! I just backed up ions_1.tpr.edr to ./#ions_1.tpr.edr.2# Steepest Descents: Tolerance (Fmax) = 1.00000e+03 Number of steps = 50000 Segmentation fault Why this coming?I also tried mdrun -nt 1 -deffnm ions.Is it due to any installation problem?I installed gromacs simply from the Ubuntu software center.I searched in mailing list also.
