How to use ToppGene ??

Question

[madkitty]

We did whole transcriptome sequencing (RNAseq) of 6 samples (3 normal vs. 3 tumor) and ended with 270 differentially expressed genes : 200 up regulated and 70 down regulated. I want to use ToppGene for Candidate gene prioritization of our 270 genes, I know that sounds stupid but I couldn't find any proper manual of toppgene written in plain English and I'm very confused on how to use this software.

Here is the link: https://toppgene.cchmc.org/prioritization.jsp

It has 2 blanks to fill, "training gene set" and "test gene set" and don't understand what should I fill out in there. Let's say, if I need to do Candidate gene prioritization of our up regulated gene set (200) what should go in training and test gene set?

Here's the link to the help file, in case, you haven't found it yet: https://toppgene.cchmc.org/help/help.jsp

From what you have stated, you can either use all 270 as the test set or do it separately (200 upregulated and 70 downregulated). I would recommend doing separately so that you will have ranked down and up candidates. You need training set though. Typically training set should be established prior knowledge (known genes associated/related to phenotype of your interest or pathway, etc.).
