Hi, Bruce,

I have written codes in MATLAB to convert ASCII data into SSRL's binary data in
order to use EXAFSPAK.  The binary format is guessed by dumping the data.  Maybe
someone can use it as a start and come up with a plugin for Athena.

Tsu-Chien,

Very helpful!  Thanks.

If someone can supply me with a few files of test data in the SSRL
binary format, I will can put an SSRL plugin on my list of things do
do.
