Notes from testing/user feedback of beta v2 software



Fill in gotchas, observations of user behavior etc for the v2 software

(dont enter bugs here, use Gsea_enhancements instead

I ran gsea v2 and the results not identical to PNAS published results. Theres a bug!

Probabaly not

1) your results modestly different - FDRS change a bit or the order of top gene sets is a little different
This is because the FDR for a small number of sets can be a bit choppy in the tail. So, a small diff (few percent) in FDR is not unusual as the random seed used from run to run is different
Additionally, the mapping databases have been updated to reflect the latest releases of NetAffx, Unigene and related chip annotations. These changes might have affected the mapping of gene sets from native ids to gene symbols and also the collapsing of datasets from probe ids to gene symbols. Our internal tests show that these effects are minor but nevertheless could account for small differences in FDR

2) The results are hugely different
Something is wrong and its most likely your fault.





GSEA Java Needs

Needs 1.4+
Preferred to use 1.5

So if you launch on a mac and see the error message unsupported class version it means that your mac (or windows) doesnt not have the correct java version.
For the mac: http://docs.info.apple.com/article.html?artnum=302412
