issue with SICER input files

Hello,

I’m using SICER peak calling tool, as inputs I uploaded 2 BED files (one control, one ChIP tag file). When I want to execute the job, first file (whatever it is, control of ChIP file) is enlighten in red with that error message:
SICER is not available for the genome.

Does anyone would know what I could do to fix it?

Many thanks for your help,

Pierre
