Hi Mark,

I tried to run an individual tpr file and it crashed:

Double sids (0, 1) for atom 26
Double sids (0, 1) for atom 27
Double sids (0, 1) for atom 28
Double sids (0, 1) for atom 29
Double sids (0, 1) for atom 30
Double sids (0, 1) for atom 31
Double sids (0, 1) for atom 32
Double sids (0, 1) for atom 33
Double sids (0, 1) for atom 34
Double sids (0, 1) for atom 35
Double sids (0, 1) for atom 36
Double sids (0, 1) for atom 37
Double sids (0, 1) for atom 38
Double sids (0, 1) for atom 39
Double sids (0, 1) for atom 40

-------------------------------------------------------
Program mdrun, VERSION 4.6.5
Source code file:
/local/software/gromacs/4.6.5/source/gromacs-4.6.5/src/gmxlib/invblock.c,
line: 99

Fatal error:
Double entries in block structure. Item 53 is in blocks 1 and 0
 Cannot make an unambiguous inverse block.


To create my tpr files I useda bash script like this:





















*#!/bin/bash -fnrep=`wc temperatures.dat | awk '{print $1}'`echo
$nrepcount=0count2=-1for TEMP in `cat temperatures.dat`do   let count2+=1
REP=`printf "%03d" $count2`       REPBIS=`printf "%d" $count2`  echo
"TEMPERATURE: $TEMP K ==> FILE: nvt_$REP.mdp"  sed "s/XXXXX/$TEMP/g"
nvt.mdp > nvt_$REP.mdp  grompp -f nvt_$REP.mdp -c min.gro -p topol.top -o
eq_$REPBIS.tpr -maxwarn 1   rm -f tempdoneecho "N REPLICAS  = $nrep"echo "
Done."*
