RE: amber-developers: AMBER 9 Problems on IRIX and ALTIX

Hi Ray,

A quick question. Does this same patch need to be applied to the sa-driver.f
file in the sander src directory as well?

There is also the same logic on line 379 of $AMBERHOME/src/pb_sasa.f

I assume this will need the same patch?

All the best
Ross
