Hi folk! This is my first post and I'm quite new to next-gen sequencing analysis, so please be kind
Here is some background on my data:
mRNA from rat heart tissue was isolated and sequenced using a Heliscope from Helicos. I then converted the sms file generated by Helicos to a fasta file using a script in the Helisphere software. From there I used TopHat to look for splice junctions.
From what I can see, everything went fine. The TopHat output includes all the files that I would expect it to include. Now, when I tried to view the .BED and .WIG files using the UCSC genome browser I have problems.
Using the input found here --> http://genome.ucsc.edu/cgi-bin/hgGateway I tried to view my files after selecting genome->rat and the most recent assembly. I try to upload my .BED file and received the following error:
"Error File 'junctions.bed' - Unrecognized format line 2 of custom track: gi|34868215|ref|NW_047355.1|Rn11_WGA1875_4 1124643 1138858 JUNC00000001 2 - 1124643 1138858 255,0,0 2 11,10 0,14205 (note: chrom names are case sensitive)"
I am wondering if I'm even attempting to use the right tool to view the file or if there is some upstream problem?
Any help would be appreciated.
Thanks,
Sam
