Dear colleagues,

I am having some trouble installing MAF datasets at our server. When I
run "Extract MAF blocks given a set of genomic intervals", I got this
error message:

"Fatal Error: The MAF source specified (10_WAY_MULTIZ_hg19) appears to
be invalid."

Below is what I did by following the wiki page:
http://wiki.galaxyproject.org/Admin/Datatypes/Add%20MAFs

1, download all mafs for hg19 from
http://hgdownload.cse.ucsc.edu/goldenPath/hg19/multiz46way/maf/

2, index them using "maf_build_index.py --species=hg19,panTro2,
gorGor1,ponAbe2,papHam1,calJac1,tarSyr1,micMur1,otoGar1,rheMac2
$file". Our user requested primates only.

3, Here is my maf_index.loc file:

Any hint on which step is wrong or missing is highly appreciate!
