[gmx-users] Memory corruption on SAS computation of a large (~1000000 frames) file

[Camilo Andrés Jimenez Cruz]

Hi all

I am using gromacs-3.3.99's g_sas_s  in a long trajectory and I get this
error right away. I assume its memory capacity, is there a way (other than
cutting the trj in smaller chunks?)
