OCEAN is the U. Washington program for doing XANES sims using ab-initio, Bethe-Salpeter methods (http://monalisa.phys.washington.edu/OCEAN/ocean-about.html). It seems to require a certain amount of experience and expertise to get it to produce any result, let alone correct results. I wonder if this might be a good forum for getting advice on solving problems with this code. Unlike ABINIT, which is one of the ab-inito engines OCEAN can use, OCEAN doesn't have a forum of its own. -- Sincerely, Matthew Marcus
