Thanks a lot Bruce! Everything went smooth with me (as you well know, I run the programs on a Mac OSX). I simply ran the horae_update command and followed instructions (the make command is run automatically, the make install I had to do myself, after being root and being in the horae_047 directory). It produced Athena 0.8.035, Artemis 0.7.013 and diana 007. I am testing the program, but not as intensely as done in the past summer. We are trying to implement feff in a simplex routine to find the best fit while moving the geometry of the metal ion surrounding .... Will let you know how things are going.
