Hi Mauro,

I use Ifeffit and Horae packages under Debian built by Carlo so launching Artemis from the command line:

If you are using a linux system, I strongly recommend compiling Ifeffit and horae from source, and indicating which Ifeffit and horae distribution you use. I cannot offer any support for the debian packages. I'm not saying the packaging is bad, or at fault here -- it is almost certainly is not. But I have no idea what is in the package, so it's pointless to try to troubleshoot it. --Matt

Hi Mauro: I wanted to close the loop on this problem. I have implemented a temporary solution while I figure out what the right thing to do is. This solution applise to whomever is using the Debian packages for etch and sid as well as my unofficial packages for sarge and the ubuntu varieties. Note that for Debian lenny you should use the sid repository. Point your /etc/apt/sources.list to whichever source applies to your distribution: deb http://debian-xray.iit.edu sarge main contrib non-free deb http://debian-xray.iit.edu etch main contrib non-free deb http://debian-xray.iit.edu sid main contrib non-free deb http://debian-xray.iit.edu edgy main contrib non-free deb http://debian-xray.iit.edu feisty main contrib non-free upgrade using whatever tools you choose. You will get a package that is names 1.3.0 but has been rolled back to the 1.2.9 version. This has been tested to not have the error that you found on etch, sid and sarge. The problem was my mistakenly believing that Matt had released version 1.3.0 in September 2006 (my fault, I should have asked!). I will keep this naming scheme until the real 1.3.0 (or 1.3.1) releases. As for the official version in Debian. i will look into what is the best thing to do to make the fix. I don't know when I will figure this out or when it will appear in etch/proposed-updates. Again, sorry for the problem. carlo On Fri, 20 Apr 2007, M. Rovezzi wrote:

I don't quite understand this. Would a screenshot or a clar project file help?

Bruce,

I use Ifeffit and Horae packages under Debian built by Carlo so launching Artemis from the command line:

$artemis&

at each fit, during the minimization process, appear in the standard output, that is in the shell where I executed the program many lines (one for each path at each minimization step, if I well understand it) that have this form:

sum path #1 #2 #3 #4

Where #* are real numbers and sometimes appears "NAN" that, as Matt said, seems a division by zero or a log(-1). I'm trying to produce a project file that will show the case when the minimization fall in all "NAN" and the loop need to be killed to stop. I'll post it as soon as possible, but in the meantime is useful to understand these numbers that appear in the shell.
