MDMR – Nicholas Schork Multivariate distance matrix regression. Explain a gene distance matrix using parameters (e.g. micro-array chip, or for us, MeSH annotation=disease) BioPython function exists. http://www.pnas.org/content/103/51/19430.abstract?ck=nck Profile comparison used to make the distance matrix? Also possible – look for pubmed co-citation (an independant distance matrix, not involving MeSH?) Regenerating generif. BG-profiles computed, appear to [...]

Towards Profile comparison results
Posted in progress, todo on April 22, 2008 | Leave a Comment »
Ballpark runtime figures – I took about 30 nuclear receptor genes and ran those against the 4000 MeSH Disease profiles – this took about 30 minutes. Extrapolating to the approximately 10000 human genes with GeneRIFs makes the runtime about 7 days. Plan for tomorrow is to pull out an example for and mock up the [...]
Biting the Bullet

A bit anticlimatic — I had previously waited forever for Entrez Gene and all the GeneRIFs to convert from XML to to text files. So rather than doing that myself, I wrote the code to load from text files on the Entrez Gene FTP server. Have other people do most of my processing and all [...]

Optimise
Posted in progress, SQL, todo on April 28, 2007 | Leave a Comment »
Sounds like a transformers yell…”Transformers, Optimise!” Anyways, thing to fix: all the CREATE TABLE AS SELECT…. create tables without keys. No key is definitely bad. Trying this for the one that really matters – the gene_term_related_citations query. EXPLAIN seems happier, but proof will be in the pudding (or the running, in this case). Dang…optimised query [...]
A cunning plan
Posted in progress, SQL on April 26, 2007 | Leave a Comment »
Time to get cracking on the optimisation. The dual plans are to Expand the TF database with taxonids (and eventually load all of Entrez Gene) Optimise queries using table indexes Looks optimistic – I like orders of magnitude improvements. Just hacked the Entrez Gene fetcher to extract the taxonid from the XML. I should look [...]
