Bruce, I have recieved the liscence to install and use FEFF8. Would you please tell me how to upgrade the FEFF6 tiral version, so that, I can use ifeffit with FEFF8 instead of FEFF6. I appreciate your help. Ahmed

Ifeffit work fine with feffNNNN.dat files from Feff 6, 7, and 8. By default, Feff8 does not write feffNNNN.dat, and you'll have to set the 'CONTROL' parameters in feff.inp to get these files. See the Feff documentation for details on how to do this, and on how to install Feff8. I should mention that the Feff6 that comes with Ifeffit is not really a trial version. Feff8 is designed for XANES calculations, and though it can also calculate EXAFS, the results are very close to those from Feff6 and definitely not uniformly better. With the possible exception of including hydrogen in a more physical way, I know of very little evidence for Feff8 being better than Feff6 for EXAFS. Hope that helps, --Matt
Hi folks, This morning I received email from a fellow at the Beijing Synchrotron Radiation Facility. He was having trouble downloading the monstrously huge Windows installer file from Matt's web site. He was a little vague about what the problem was, but I suspect that it is a combination of limited international bandwidth, distance, file size, and http connections timing out. It occurs to me that it would be useful to have mirrors on other continents. These could be entire site mirrors of the Ifeffit, Atoms/Athena/Artemis, and/or SixPack pages or they could just be mirrored copies of the most important files. In any case, mirrors might help those with limits to their bandwidth by giving them geographically closer options for downloading the big files. So, if anyone out there has been loving Ifeffit, isn't a programmer, but still has been wondering how to give something back to the Ifeffit community, establishing mirrors outside of North America would be a great contribution.

Bruce, Everyone, A 'lite' version of the Ifeffit installer that contained all the executables (and perl, and tcl directories needed by them) but no examples or docs would still be ~17Mb. Is that enough savings in download file size to help those with slow connections or very far away? My guess is 'no;, but if the consensus of those with slow connections is 'yes', I'd consider doing this. Lobbying for synchrotron facilities or EXAFS beamlines to set up mirrors of data analysis software seems like a fine idea to me. Maybe the International XAFS Society could be persuaded to do something about this.... --Matt
