[Beg-sysbiol] creating consensus modules from ensembles of clustering solutions
by Steven Maere 09 Sep '07

09 Sep '07

Hi all, I've been thinking a bit about the problem of having multiple clustering solutions and combining these into 'consensus modules'. I don't know how much and along which lines you have been working on this problem, Tom ? My first thought was to somehow cluster the weighted summary graphs that Tom and Anagha produce with their software. Weighted bipartite graph clustering algorithms might be ideally suited for this, and there are apparently some algorithms and implementations available. I've attached a few relevant articles. We could think about: - clustering the weighted bipartite regulator-gene graph produced by the more recent Lemone 'S' versions - clustering similarly constructed bipartite regulator-condition graphs, as Eric suggested, to see which conditions matter for which regulators Let's discuss further after Tom gets back from holidays.

[Beg-sysbiol] Workshop on Biological Networks, ECCS'07, 1-5 October, Dresden
by Roeland Merks 07 Sep '07

07 Sep '07

Dear all, This might be an interesting opportunity for you guys. I think this will be a really nice conference; it is broad, but there are continuous biology sessions. No need to attend the sessions on traffic modeling or econophysics :-). I am speaking at another satellite conference (developmental biology) on 5 october. Cheers, Roeland ---------------------------------------------------- From: Fatihcan Atay <atay(a)member.ams.org> Date: Fri, 31 Aug 2007 23:57:08 +0200 Subject: Workshop on Biological Networks, ECCS'07, 1-5 October, Dresden Genetic and Biological Networks: Models, Dynamics, and Simulations A satellite workshop of the ECCS'07: European Conference on Complex Systems, 1-5 October 2007, Dresden, Germany Biological systems show emerging functional properties originating from their many interacting units and their inherent multi-level structure. In recent years, biologists, physicists, mathematicians, and computer scientists have been joining efforts in order to understand the different aspects of the collective phenomena exhibited by aggregates of cells and by regulatory networks. The aim of this meeting is to bring together experts in such fields to discuss and explore our understanding of complex biological networks and their applications in the life sciences. Specific topics include, but are not limited to, gene-regulatory, molecular, and metabolic networks, bioinformatics, population dynamics, neural systems, evolutionary dynamics, and mathematical biology. Interested researchers who wish to contribute a talk are invited to send a title and abstract to fatay(a)mis.mpg.de For further information please visit: http://personal-homepages.mis.mpg.de/fatay/eccs07 ---------------------------------------------------- -- ================================================================== Roeland Merks Group Leader "Plant Systems Modeling" Tel:32 (0)9 3313695 Fax:32 (0)9 3313809 VIB DEPARTMENT OF PLANT SYSTEMS BIOLOGY, UGent Technologiepark 927, 9052 Gent, BELGIUM roeland.merks(a)psb.ugent.be http://www.psb.ugent.be ==================================================================

[Beg-sysbiol] [Fwd: Fwd: urgent: visit of Gladis Casas and Maria del C.]
by Yves Van de Peer 05 Sep '07

05 Sep '07

Dear All, September 14th or 17th (not really sure ...) two Cuban students will arrive for a short stay (in the framework of VLIR, like Isis) in the lab. They work on networks (if I'm well informed, which is not always easy dealing with Cubans :-), and it would be nice if you could help them a little with their project, as Yvan did with Isis. Cuban students are pretty smart, but need sometimes a bit of guidance and I hope you can find some time to talk with them and exchange some ideas, and make them feel welcome. Many thanks in advance, See you in 3 weeks :-) Yves -------- Original Message -------- Subject: Fwd: urgent: visit of Gladis Casas and Maria del C.

Ze waren dus blijkbaar van plan om de 3 maanden in Gent te verblijven maar de eerste maand naar Hasselt te pendelen. Dit lijkt mij niet echt efficient. Van Yves begrijp ik dat in Gent alles reeds geregeld is. Misschien is het daarom beter om die studenten de eerste 2 maanden in Gent te laten, en dan is er tijd om de verhuis naar Hasselt te plannen. De reservatie van de kamer in Gent in korten tot 2 maanden is misschien nog mogelijk, in elk geval minder lastig dan die kamer nu te gaan annuleren. Dit is natuurlijk in de veronderstelling dat er nog geen kamer voorzien is in Hasselt, en Koen (of andere medewerkers) beschikbaar is half November. Wat denken jullie?
