I have downloaded my ChIP-seq data which I aligned to the human genome using Bowtie for Illumina on Galaxy, and have installed MACS on my computer (4Gb RAM) and gotten it running in CMD/DOS.  Unfortunately my data files appear too large to run locally (25Gb [90 000 000 lines] input control, 30Gb [120 000 000 lines] ChIP). When I run MACS14 it returns:

Traceback (most recent call last):

File "", line 366, in ,module.


File "", liine 60, in main

(treat, control) = load_tag_files_options (options)

File "", line 355, in load_tag_files_options

ttsize = tp.size()

File "C:\Python27\Lib\site-packages\MACS14\", line 759, in tsize for x in rage(nc):


Is there any way for me to run this analysis (peak finding) on my computer? I can gain access to a 12Gb RAM computer, I just need to move my data files. Would that work, or do I need to look at running the analysis on a server? I don't have access to a server so I think I am stuck at this point.

Thanks for your help.

If there is a computer with more resource available, then it seems worth trying that first. It does mean starting over from install. A Cloud Galaxy is another choice. AWS offers grants for research projects.

Best, Jen, Galaxy team
