Hi Bruce, hi Matt, the other day a colleague encountered a problem. He measured a ZnO standard. I have the ZnO.fpj project file and can share the data. It is about 1.2 MB in size though. Shall I upload it to a public file hoster or sent it to your email account? At first I thought this is a problem with my installation steps on Fedora 18 x86_64, but I could reproduce the problem with Ubuntu 12.04 i686. The line numbers match, so I will post only the output from dartemis on Ubuntu. Note: this file was created with the Windows version of Demeter on Windows 7 Enterprise 32bit (running on Fedora 18 x86_64 as VirtualBox 4.2.18 virtual machine). Demeter crashes in the Windows version as well using the steps below. steps to reproduce: * start dartemis from a terminal * open project file in dartemis through 'Artemis [EXAFS data analysis]' window: File -- open project * in the 'Artemis [Plot]' window click on [R] button * in 'Artemis [Data] ZnO' window click on the bull's eye sign to the right of rmax window * wait about 10 seconds; dartemis will crash with the below error message ### Ubuntu 12.04 i686 test@test2:~$ dartemis Attribute (bft_rmax) does not pass the type constraint because: Num is not larger than 0 at accessor Demeter::Data::bft_rmax (defined at /home/test/perl5/lib/perl5/i686-linux-gnu-thread-multi-64int/Demeter/Data.pm line 406) line 7.
