I have done GO enrichment analysis using GOSeq and got the lits of GO terms associated with my DE genes. Then i used REVIGO to visualize the list of GO terms and found some interesting clustering. Now my question is how do i know how many genes are there in that particular cluster and also whether those genes are up or down regulated?

Thanks Upendra

Each gene must display multiple GO id's. So, you have to make a table, where column1 is GO id's , column 2 is p-val, column 3 you have to generate, which will say Gene Name (so this repeat for the gene name which has multiple GO id's) and column 4 with the FPKM/RPKM value. So, you Revigo control(input) file will look like this

% GOterm        enrichment_P-value    Gene    FPKM
GO:0022402      1.74E-15    Elf1    2.3
GO:0007049      5.43E-1    Elf1    3.5
GO:0010447      2.74E-8    Nanog    -1.3
GO:0000027      2.43E-3    Nanog    -3.5

Now, in the scatter plot, just sort the axis by userValue_3 and you should see clusters which are based on your expression value.

Cheers
