I've been configuring my local instance of galaxy to use trackster according to the instructions on 
https://bitbucket.org/galaxy/galaxy-central/wiki/Visualization
when I run the script:
python ./cron/build_chrom_db.py ./tool-data/shared/ucsc/chrom/

I get files that begin with:

        <META http-equiv="Content-Script-Type" content="text/javascript">
chr1    247249719
chr1_random     166326
...

this causes an error in the browser:  "Could not load chroms for this dbkey:"

if i delete the first line " <META http-equiv="Content-Script-Type" content="text/javascript">"
from the .len file,  then trackster works fine.

I'm thinking there is a new line the input to  build_chrom_db.py that is not getting stripped by this script


thanks,

Curt Palm
