cliques clans and complexity analysis

We've come a long way since proteins in pools by probability. Cliques provoked research into how best to validate their worth, which led to hamming distances, densitrees, splitstrees, and more.

My latest development milestone is the first working version of the perl code I've written for annotating proteins with their functions. I had a version of this code previously that did so for all cliques, but this time, I wanted to only handle the cliques indicated by Jim's MatLab code.

The script works great, and outputs all cliques by binary signature, listing proteins and functions, and outputs the list of strains. Both on Octopussy and on my netbook, execution took just over an hour.

 

My next undertaking will be speeding the code up as much as possible, so that when I rework it to sit on the edwards.sdsu server with form submission, it will actually be usable in speed. The move to a web-based tool will of course include some other major headaches, but task one is getting the complexity analysis done and making strides towards speeding it up. example from splitstree.org

In the spirit of ample blogging, I'm posting the link for a paper the math guys and I have been fighting our way through. Enjoy!

update: eeepc ubuntu display issues

Hazzah! Display hook up and disconnect now works without hiccup, Compiz Fusion was indeed the culprit. Lots of ways to go about fixing it, some folks had command-line methods in the forums, but often those would require either running the command yourself each startup (or at least each startup when you're planning on using an external display), or automating that code to run each boot. My method seems a bit easier, I just went into the package manager (System->Administration->Synaptic Package Manager) and searched Compiz, and marked all parts for complete removal. Metacity is probably already installed, so it will take over for Compiz as soon as the removal takes place, but while you're in package manager, double check to be sure you have Metacity already installed, and if not, go grab it. I'm sure there are other alternatives, both in methodology and in which display driver you replace compiz with, but this fix worked for me!
 

eeePC+ ubuntu display problems

I was comforted to see that Josh's netbook locks up when an external display is connected too, and that I wasn't the only one having that issue. A little forum hunting found that it has to do with compiz fusion. Disabling (and removing) compiz and instead using Metacity seems to have worked for others, I'm in the process of trying that fix right now, and I'll write it up if it works. Fingers crossed...
