Custom genomic regions should be provided in BED format and can be given by admire -r regions1.bed -r regions2.bed ....

Hint: Use multiple -r parameters to analyse more than one region at a time.

Hint: The BED format is described here.

To enable the Gene Set Enrichment Analysis for a certain bed file, include a gene_name property in column 4 of the bed file:

chr1    213941196   213942363   gene_name=gene1
chr1    213942363   213943530   gene_name=gene2
chr1    213943530   213944697   gene_name=gene3
