Fisher exact test

Hi, I would like to use Fisher’s exact test to obtain p-values for gene enrichment. I have seen reference to the use of cross-tab (local) and an example of cross-tab use for Chi-tests. but I don’t know how to provide the data for a contingency table (2 x 2) in order to produce the p-value. Does anyone have any examples they could share?

Many thanks in advance.

Hi @0nly4phil -

You could provide that data manually using for example a Table Creator node. If you have only two rows in your dataset, the Fisher’s exact p-value will be calculated.
