Hi, I have locally installed galaxy on a linux(ubuntu) machine. I have not installed all the tools on the local galaxy server. I am not able to integrate MACS peak calling tool with galaxy. I have followed all the instructions for installation of MACS and it is running fine on the commandline(standalone is fine).But with galaxy it is giving the following error: "An error occurred running this job: /bin/sh: macs: not found" I have tried executing the macs_wrapper.py in the commandline and I have got the following error: "Traceback (most recent call last): File "macs_wrapper.py", line 135, in <module> if __name__ == "__main__": main() File "macs_wrapper.py", line 45, in main options = simplejson.load( open( sys.argv[1] ) ) IndexError: list index out of range" I have set the PYTHONPATH(i.e PYTHONPATH=~/galaxy-dist/lib) and I have macs in PATH. I am not a technical/computer expert as well, hence I would appreciate if any one could help me resolve this problem & tell me where I am going wrong Thanks in advance Regards
