Updates and Delays

July 12, 2010 by John No Comments »

I was hoping to bring you the latest Olex2 1.1 release for all supported OS but unfortunately it has been hampered by Fedora 13 linker issues with OpenGL. I expect to roll out Fedora 11, 12 and Centos 5 tomorrow morning to the testing repo along with a new CCTBX and Olex2-gui 1.1. I will continue to work to try and track down the anomalous Fedora 13 behaviour. I may even finally move over to the scons setup supported by the Olex2 team and finally retire my old Makefile? Perhaps not depends if I can figure out the mad build directory structure created by scons and if it is any better?

Also expect the latest platon for Fedora 11, 12, 13 and Centos 5 at the same time.

Fedora 13 is coming soon. The infrastructure on Debroglie is ready. Little by little the repository for fedora 13 will be populated.

planet, bug tracker

March 20, 2010 by Pascal Comments Off

Two new things today:

I replaced trac with redmine. It’s in ruby and quite tricky to install on Centos but I recently found a nice tutorial (Redmine on Centos [fr]). So here is the link: http://redmine.debroglie.net.

I just set up a planet on Debroglie after some discussions on the x-ray forum and John. If you have a rss feed for your software, blog, website… You can register as long as it’s talking about crystallography. The link is: http://planet.debroglie.net.

 

Superflip

March 18, 2010 by Pascal Comments Off

superflip has been updated for all fedora platforms. Centos version has not been updated due to a too old compiler. I sent an email to Lukas about it.

 

Python 2.6 and centos

March 15, 2010 by Pascal Comments Off

There is a review request for python 2.6 on bugzilla for centos 5: https://bugzilla.redhat.com/show_bug.cgi?id=573151

When this is going to be pushed to EPEL, all dependances on python 2.5 will be replaced by this new python 2.6 and python 2.5 rpms removed from the Debroglie centos repository.

 

anafcfweb

March 1, 2010 by Pascal Comments Off

I wrote a small script that plot a few graphs from fcf files:
Anafcfweb

The script is in alpha stage with some improvements needed. I do not store the fcf/cif file on the server. However, the eps/png/pdf generated files are stored in a temp folder not publicly accessible.

It’s written in pure php. The original script was in python but I ported it to php because of the poor perfomance of the cgi interface on Debroglie. I also have an opcode cache for php, so it’s much faster.

About the html part, the graphs are rendered with flot. Flot is a plotting library using canvas. I tweaked it a little bit so it gives better performance with the thousands of data points that requires the graphs. Canvas is part of HTML 5 so do not expect any support in Internet explorer. The script is using a compatibility layer called excanvas for IE but it is extremely slow…

Everything is not rendered in canvas, so export of the graph is not possible directly. For this purpose I am generating a picture from the server with gnuplot. There is also a CSV export of the coordinates.

The graphs are interactive, you can peak a reflection to show all the variables, modify the weights and filter the reflections.

Almost everything is done via javascript and the script heavily depends on jquery.

The sources are here : Anafcfweb svn.

Planet, Platon, CCTBX

February 24, 2010 by John Comments Off

Ok, so the planet has stalled slightly because the simplepie feed catcher is running out of puff on the cron process and getting killed.

Platon has been updated and all good and there is now a new cctbx in the testing repo.

Enjoy

 

Planet Feed Crystallogaphy

February 17, 2010 by John Comments Off

Ok, so Pascal’s great idea and an idle lunch have seen me install a feed aggregator on the forum. Now this post will let me know if it is updating automatically! How cool is that?
