Hi Andrea,

this is my input for the minimization:

#Minimisation
grompp -f EM.mdp -c 1KAL_SOLV.pdb -p 1kal.top -o 1KAL_MINI.tpr mdrun -s 1KAL_MINI.tpr -o 1KAL_MINI.trr -x 1KAL_MINI.xtc -c 1KAL_MINI.pdb -v -e 1KAL_MINI.edr

Hi Giacomo,
you are using the flag -c twice. Check your input line in the shell. See mdrun -h for more information.
It should be something like:
mdrun -s file.tpr -o file.trr -c file.pdb
probably you have
mdrun -s file.tpr -o file.trr -c -c file.pdb
-------------------------------^
a typo error

Regards


Andrea

Hi Tsjerk,

I have just fixed the problem of cyclic (manually deleted some bonds
that gromacs added...), I got everything ready for the minimization
step after genbox.
I run it and it says:

Program grompp, VERSION 3.3
Source code file: statutil.c, line: 549

Fatal error:
Double command line argument -c

Is there anything wrong with my inputs?

thanks a lot

yes. it is exactly what it says.
