[Users-list] Obtain GRIN failed in tut. greater01, although I checked the path for grid and grub.dat in the option...

[Hua Wong]

I tried to do the Greater tutorial greater01.

So I cd to the forementionned directory, launched Greater and added  
target PDB.pdb.

Instead of "ready" I obtain "GRIN failed"

Have I forgotten something?

In the options (as in the FAQ it is designated as a source of  
numerous "GRIN" error question) I checked that paths were correctly set.

GRID path is set to : /users/invites/wong/mygrid/
grub.dat file is set to : /users/invites/wong/mygrid/grub.dat

Is there other options I have to set? Apart from those two obvious  
ones...
