[gmx-users] how to direct log file correctly?

[Albert]

Hello:

  I found that each time I submit gromacs job in GPU workstation, the 
log file always in my terminal screen, like:

imb F  1% step 13700, will finish Wed Apr 17 17:57:20 2013
imb F  1% step 13800, will finish Wed Apr 17 17:57:20 2013
imb F  0% step 13900, will finish Wed Apr 17 17:57:20 2013
imb F  0% step 14000, will finish Wed Apr 17 17:57:20 2013
imb F  1% step 14100, will finish Wed Apr 17 17:57:19 2013
imb F  0% step 14200, will finish Wed Apr 17 17:57:19 2013
imb F  0% step 14300, will finish Wed Apr 17 17:57:19 2013
imb F  0% step 14400, will finish Wed Apr 17 17:57:19 2013


I am using command:

mpirun -np 2 mdrun_mpi -v -s nvt.tpr -c nvt.gro -g nvt.log -x nvt.xtc
grompp_mpi -f npt1.mdp  -c nvt.gro -p topol.top -o heavy.tpr -n
mpirun -np 2 mdrun_mpi -v -s heavy.tpr -c heavy.gro -x heavy.xtc -g 1000.log



I am just wondering how can we direct the log file correctly? Meanwhile 
tho job won't have any problem going to next step (I am running all the 
steps in one script).

thank you very much
best
Albert
