Sorry, Bruce, if my wording confuses you. Thank you for considering helping me! 1. I didn't edit any content of the log file. I simply copied and pasted the lines showing up in the log file when Artemis failed. Again, the message showing in the log file is: "Can't call method "workspace" without a package or object reference at C:/strawberry/perl/site/lib/Demeter/Fit.pm line 1550." or sometimes: "Can't call method "group" on an undefined value at C:/strawberry/perl/site/lib/Demeter/UI/Artemis/Project.pm line 466." 2. I simply don't know how to replicate the problem on a different computer, because Demeter seemed to work fine on other computers that I tried. This computer that has Artemis problem is my work computer and some experiment data can't be transferred onto my home computer to work. Demeter also seemed to work fine last week and only stopped working yesterday. I didn't update anything on my work computer, so I don't know what is causing the problem. Sorry I can't do more to help report the problem, except providing you with the messages in the log file! This problem is also independent on whatever project files I'm using, so sending you project file wouldn't help. I used to create new ***.prj file using simple feff.inp and click "save project". Next time, I re-opened this new file and Artemis would close. Sorry for the inconvenience brought to you since the problem can't be reproduced anywhere else! Can you help me to understand what the error messages mean? or give me advice on how to check or clean my computer to make Artemis work better? Thank you very much for your time!

I'm unfamiliar with this problem. Two points:

1. It is a very bad idea to edit the contents of the log file in a bug report. Unless you are intimately familiar with the code, the likelihood of leaving out something of value to me is quite high.

2. Without an example or a very clear recipe, I have no chance of reproducing the problem on my own computer. If I cannot reporduce the problem the likelihood of being able to fix the problem is so small it is not worth my time to even try.

I'm inclined to help you, but you have to submit a decent bug report.

P.S. I get REALLY tired of repeating myself on this topic. One of these days I am just going to start ignoring emails that do not provide actionable information.

Dear all,

I'm using Demeter version 0.9.18.2 in Windows 7 Enterprise. Starting from yesterday, I could not re-open what I saved as ***.fpj any more. I tried to re-open my previous projects as well created new projects and then re-opened them. Artemis program would close after spending 1 or 2 seconds in trying to load what I asked it to load. Mainly, the following two error messages were showing in the log file in the %APPDATA%\demeter when I tried to open different project files:

Can't call method "workspace" without a package or object reference at C:/strawberry/perl/site/lib/Demeter/Fit.pm line 1550.

Can't call method "group" on an undefined value at C:/strawberry/perl/site/lib/Demeter/UI/Artemis/Project.pm line 466.

I only had problems with loading ***.fpj files. Athena projects and feff input files can be imported in Artemis as normal.

Thank you very much if you can help to fix the problem!

Are you quite sure that is the only text in the log file?

Demeter first writes several lines about the environment in which Demeter is operating. The error message is almost always followed by several lines of backtrace. All of that provides context for me to understand the proximal cause of the problem. If you extract a part of the log file, then that context is lost to me.

yesterday. I didn't update anything on my work computer, so I don't know what is causing the problem.

Artemis worked on that computer last week and does not work this week? And you did nothing to change the computer? Something doesn't add up.

Did your anti virus software update? Did your institution's system administrators perform an update? Did you install any new software? Anything? It's hard for me to understand how the behavior of the program can change simply by walking away for a few days.

Without being able to watch this on one of my computers, I can only guess what the problem might be by examining the two lines of code you cite.

My best guess is that something is preventing you from unpacking the project file. An .fpj file is nothing more than a zip file with a different file extension. It gets unpacked in %APPDATA%\stash (where %APPDATA% is the location of the log file). That means that you have to have permission to write files to that location. So, my best guess is that something is preventing you from writing to that space. I have no guess for what the cause of that is.

So, check the permission of that folder. Try making a file in that folder by hand. Try extracting a zip file buy hand into that folder.

If not that, then I'm afraid I'm out of ideas.
