Here are some hints on writing an actionable bug report: http://bruceravel.github.io/demeter/documents/SinglePage/bugs.html In general, it is wise to provide enough information (like, say, the project file causing the problem) that the problem can be reproduced elsewhere. If you won't offer enough that the problem can be reproduced, it is unreasonable to expect a useful response. That said, I think I know your problem I suspect the problem is in the CIF or atoms.inp file that you are using. The ":2" in your space group symbol "I 41/a m d :2" is non-standard notation. Well, "non-standard" in the sense of not understood by Demeter. You have two choices: 1. Edit your atoms input data to remove the ":d", throw away your current project file, and start over again. 2. Try the preview release of Demeter 0.9.26 at http://bruceravel.github.io/demeter/#windows. Dealing gracefully with ":1" and ":2" notation is a thing that I've tried to fix.

Hello,

I wonder if anyone can help me. Artemis (version 0.9.25) is unable to open the most recent project files that I have created and just crashes. These files also can't be opened on a different computer. I get the following message in the dartemis log file:

So I guess I need to define a method name? What could it be and how do I define it? Thank you for your help (in advance!)

Best wishes,
