Hi Matt, Thanks for that, I shall give that a go. Can Ifeffit/athena combine two data sets and average them? Regards William On Thu, 7 Oct 2004, Matt Newville wrote:
William,
First, if you remove the last line of the file:
END OF DATA
The data in this file will be read just fine by Ifeffit/athena.
Second, if you add any of the following characters: '#', '%', ';' to the first non-blank character on the 'header' lines: #&SRS #SRSRUN=55267,SRSDAT=040521,SRSTIM=125128, #SRSSTN='ex1a',SRSPRJ='xrsws7p1',SRSEXP='exafs ', #SRSTLE='KFe3 ' #SRSCN1='80K ',SRSCN2='two ',SRSCN3='three ', #&END,
the header lines will be kept as strings -- not a big deal, but convenient.
Those steps seem easy enough that a simple filter script (in perl, bash, or python or whatever) could be written to convert Daresbury files to a format easily read into Ifeffit, athena, or sixpack. In principle, ifeffit source code could be changed to support this format, but it seems close enough that a simple filter would be better.
Finally, I couldn't tell exactly what the columns in the file were. It looked like the first column might have been monochromator angle or steps, not energy. If that's the case, you might want to look at
http://cars9.uchicago.edu/cgi-bin/ifeffit/faqwiz?req=show&file=faq03.004.htp
for hints about how to convert steps to energy.
Hope that helps,
