Dear All, Sorry for resurrecting this old thread but I've been experiencing a bug that produces very similar symptoms and that I guess may be related; but that won't be solved by Bruce's fix. Details are as follows: Software: Demeter 0.9.18.2 and 0.9.20 x64 (possibly earlier releases too) on Windows 8.1 x64 (I've never observed this bug on Windows versions before 8, but I've been using Windows 8 as my main OS for a while now so that may be coincidental) Steps to reproduce: I run a fitting project using quick first shell fits and save it. When I re-open the project around 80% of the time the problem occurs. Symptoms: When I re-open the project around 80-90% of the time one or more of the following occurs: - One of the quick shell paths completely loses all its information (including path information which isn't editable by the user, parameter info etc; see attached screenshot) - Parameter info for one or more paths is reset to the default (i.e. if I've named a path delrauau it's renamed dr_ag_au_1) - In the GDS window starting values for parameters that have a non-zero starting value are set to their previously guessed value, rather than the starting value I set (ie. If I set ss as 0.003 and during the fit it is guessed to be 0.001 when I reopen the project the starting value will be set to 0.001) and "restrain" parameters are changed to "guess". - Phase correct fitting boxes are unticked (sometimes in an "impossible fashion" where the "plot with phase correction" option is set but no paths have the "use path for phase corrected plotting" option set) Attachments: Noinfo.png - screenshot of Artemis when path info is lost Reset.png - screenshot of Artemis when parameter names are reset Dartemis.log - Artemis log file when opening a project that has this problem Artemis.fpj - Artemis project file that displays these symptoms. Please let me know if you need further info/files. Thanks, Ian Ps: OK, things got weird while preparing this bug report: The file in question stopped opening at all - Artemis loaded and went through loading fit x, x+1 etc., once it finished (not exactly sure what stage) it just closed. And then, after several attempts, started working again, as if by magic, before I'd saved a log file.... If I can figure out how to reproduce this I'll send more info... -----Original Message----- From: ifeffit-bounces@millenia.cars.aps.anl.gov [mailto:ifeffit-bounces@millenia.cars.aps.anl.gov] On Behalf Of Bruce Ravel Sent: 29 August 2014 21:59 To: XAFS Analysis using Ifeffit Subject: Re: [Ifeffit] save Artemis project and cannot find Path List information when reopen On 08/29/2014 12:30 PM, Matt Newville wrote:
I think this might explain random problems saving fits that I've seen but could never figure out how to reproduce well enough to submit a report. I'm pretty sure this happened to me during a recent "live demo" of Artemis.
Yikes! That's just swell....
Great to hear that the problem is identified!
I agree. I am grateful to Yanyun for reporting it and for bearing with me, as it took several emails for me to understand the problem. My solution, which I wrote this afternoon and which will be in the next release, was to disable the "Run Atoms" and "Run Feff" buttons the first time you drag and drop a path from the Feff calculation onto a data set. Another solution would be to preserve the results of previous Feff runs from the same Feff window. That is certainly possible, but certainly involves a lot more code than what I did this afternoon!
