[gmx-users] error in equilibration

[shiva birgani]

Dear Justin
I fallowed your tutorial of "Protein-Ligand Complex" to simulate a peptide
associated with acetic acid. All the step was good but in Equilibration
phase 1 I encountered with this error

WARNING 1 [file nvt.mdp, line unknown]:
  Unknown left-hand 'continuation' in parameter file

WARNING 2 [file "topol.top", line 1453]:
  For energy conservation with LINCS, lincs_iter should be 2 or larger.
  You can safely ignore this if your system doesn't have any
  LINCS-constrained bonds;
  for water molecules we normally use the analytical SETTLE algorithm
  instead.
Setting gen_seed to 261405
Velocities were taken from a Maxwell distribution at 300 K

There were 2 warnings

Program grompp, VERSION 3.3.3
Source code file: grompp.c, line: 1132

Fatal error:
There were 1 error(s) processing your input

how should I do correct it?
thanks in advance
