Subject: Error in annotation tools

Hello,

I'm using Nebula and when I try to use the annotation tools (genomic annotation and gene annotation in NGS annotation menu) I got always this error despite of the bed file that I use: 

An error occurred running this job:Unable to run this job due to a cluster error

Could you indicate me how to solve this?

Regards,
Gema
