[gmx-users] Floating Exception - ngmx

[Bartlett, Gail J]

Hi,

I've installed gromacs on a solaris box. In going through the tutorial
material and when I try to view the trajectory of the c_peptide using
ngmx, I get a floating exception - the ngmx program flicks up for a
second and then disappears. What have I done wrong?! Any help gratefully
appreciated. Best regards,  Gail

ngmx -f cpeptide_md.trr -s cpeptide_md.tpr
