1The 26 GO categories found to be significant at the nominal 0.005 level of the LS permutation test or KS permutation test (sorted by values of the LS permutation test). For each GO category, the table lists the unique identifier, the number of genes in the project gene list that belong to the GO category, and the LS and KS values.
The presented GO categories are ordered by the value of the LS test (smallest first).
2Goterm: CC: cellular component, BP: biological process, and MF: molecular function.
3Fisher (LS) statistic is defined as the mean negative natural logarithm of the values of the appropriate single gene univariate test.
4Kolmogorov-Smirnov (KS) statistic is used for testing if the values are of a uniform distribution.

1The different GOterms: CC: cellular component; MF: molecular function; BP: biological process.
2Genes found to be differentially expressed with a parametric value of less than 0.05 in the top 5 of GO categories.
They are ordered by the parametric value associated with the GO category for each class.
