[Ifeffit] running ifeffit under 64-bit windows7

[Sameh Ibrahim Ahmed]

Hi,

I have used ARTEMIS to fit the EXAFS of a simple Cu foil with the two
diffrent machines, a 32 bit and 64 bit ones, both running widows7, 32 ans
64 bit respectively.
The results obtained are slightly different, I have appended the message
with these results. the very low value of R-factor produced with the 64bit
system is difficult to interpret. the questions are;
1- how to account for these differences?
2- if I to publish something, which measure of the quality should I
present? and how can I interpret it?

regards
Sameh
