[gmx-users] Segmentation fault in make_ndx

[Jair]

I'm running make_ndx to create a index file with informations of groups of 
atoms.

   make_ndx -f protein.gro -o index.ndx

But in one of these calculations, when a try to create a group of atoms from 
the first to the 779th atom (or whatever), an error occurred:
....
> a 1-779

Segmentation fault
....

Somebody knows what's happening
Thanks
