Hi Everyone, I figured that it had been long enough for version 1.0071, so posted version 1.0072 today. This version has several small feature improvements and bug fixes. There is also a fairly substantial changes to the 'configure ; make ' on Unix, so that the perl and python extensions are no longer built during this process, but have to be built after installation of the library, with the 'normal method' for these languages: cd wrappers/python python setup.py install cd wrappers/perl perl Makefile.PL ; make install This change greatly simplifies the work of the configuration script and is much more reliable. The other major change is that the internals of macro handling were largely rewritten so that nested macros work correctly in all cases (including on windows). Related to that, macros that are run by feffit() and minimize() at each iteration of the fitting loop now run correctly as well. I have a Windows dll ready, but am having difficulty making standalone executables from the ravelware perl scripts. Hopefully that will get worked out soon so that a new Windows installer with the latest athena, artemis, and tkatoms, as well as gifeffit and samxas will be possible. I've also started (but haven't gotten very far on) an annoted collection of ifeffit scripts, intended to be something of a 'how-to' or 'cookbook' for ifeffit commands that will complement the documents and FAQ. Any suggestions or comments on this would be very welcome. Finally, I am really expecting that 1.0072 represents a nearly complete version of Ifeffit 1.0. I believe the XAFS analysis functionality is more-or-less complete at this point. I'm willing to fix bugs, and add small features, but would like to try to leave this version stable and to start working (even if slowly!) on much more significant changes that would eventually become Ifeffit 2. Thanks, --Matt
