[Users-list] Hydrophobic potential calculation

[Hua Wong]

Well. I've begin fumbling with the grid packages. I am not using the  
GUI because I wish to learn how to use Grid and automatize some  
operations too...

I wish to do a hydrophobic potential calculation similar to that...

Can I have a hint about the important parameters I should set in  
grid.in?
Do I have to use the DRY probe?

Most importantly, is there a size limitation for the system?
I tried with a small part and it seems to run, while the whole system  
(roughly 8000 atoms) returns me the D475-E message...

Is there a way I can get around this problem?
