[Ifeffit] SSRL data format

Hi All, Sam Webb's "SamView" which is part of SixPACK opens SSRL data files and you can then save them in ASCII format. I think he he has the source code posted on his website. Matt On 1/17/07, ifeffit-request@millenia.cars.aps.anl.gov < ifeffit-request@millenia.cars.aps.anl.gov> wrote:

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.

Question 3 at this FAQ page: http://cars9.uchicago.edu/iffwiki/FAQ/HoraeQuestions explains in some detail what kind of data Athena is able to read. Obviously SSRL's binary format cannot be imported without the use of a plugin.

It would be possible, in principle, to write a plugin that is capable of reading the SSRL binary format. However, to my knowledge (which certainly may be faulty) the technical details of the SSRL format are not published any place where I can find them. That's something of an impediment. ;-)

It would most certainly help to convert to an ascii format. Not having worked at SSRL since my grad school days, I don't really know how to do so. Your beamline scientist should be able to help you with that. Perhaps someone on the list will know the details.
