Ah, I see now.  I misread the initial post.  The help paragraph in g_sas made no 
mention of this feature, but it is indeed listed.

Naming conventions?

I've never heard of anyone needing to use this feature, as the definition of 
hydrophobicity is generally quite robust.  I would suggest trying the default 
behavior first to determine if the result is suitable, unless you've already 
done this, in which case it would be useful to discuss if you have any 
reservations about the output you obtained.
