Hello Kathryn,

This is occurring on your local Galaxy install? Have you installed the actual MACS tool and set up the proper configuration paths? Details for how to do this are in these wikis:
http://wiki.galaxyproject.org/Admin/Config/Tool%20Dependencies
http://wiki.galaxyproject.org/Admin/Tools/Tool%20Dependencies

Apart from that, I should let you know that prior to running MACS, groomed fastq datasets first need to be mapped. An example can be found in our Using Galaxy paper, protocol #3. Links to the paper and supplemental materials (including a screencast walk-through) are available here:
https://main.g2.bx.psu.edu/u/galaxyproject/p/using-galaxy-2012

If you need more help with your local install, directing questions to the galaxy-dev@bx.psu.edu mailing list would be best,

Thanks!

An error occurred running this job: /bin/sh: macs: not found

Anybody can kindly provide some hints?

Thanks,
