Hi all,
I am trying to make centre of the bilayer so I used following command line
trjconv -f 20nspopc.xtc -centre rect -o 20nstrjout.xtc -n water.ndx based on
http://www.gromacs.org/pipermail/gmx-users/2003-June/005995.html
here I selected 3 (solution) again 3 (solution) for output of the selecting
group
this command ran fine
when I feed 20nstrjout.xtc to g_density
g_density -f 20nstrjout.xtc -s em.tpr -d z -o waterden -n water.ndx
Group 0 ( System) has 14036 elements
Group 1 ( POPC) has 6656 elements
Group 2 ( SOL) has 7380 elements
Group 3 ( SOL) has 7380 elements
Select a group: 3
Selected 3: 'SOL'
Reading frame 0 time 0.000 Segmentation fault
where is the mistake happening?
Could anyone tell me
Thanks in advance
