Subject: [Genome] bigwig on microbial genome browser
To: [email protected]


Dear UCSC staff,
I am working on E. Coli genome for the first time. I am trying to use
microbial genome browser as I usually work with standard genome browser. I
have to work with a custom track which is very large, so I thought to use a
bigWig file.
But I cannot use fetchChromSize.sh since it says "ftp command failed
ERROR: sorry, attempt to fetch chrom.sizes has failed ?"

Later, I created an "artificial" file (similar to those for hg19, for
instance), with the only line
chr     4639675

since Coli has one unique chromosome.

The bigwig was created but microbial browser told me "Unrecognized format
line 1 of
http://dl.dropbox.com/u/4632963/COLI/e_coli_k12_HD30.flexibility.bw: &�
 (note: chrom names are case sensitive)"

Maybe there is a problem with bacterial genomes where chromosomes are
unique?
Or maybe it is not possible to use bigwig format on microbial browser?

Anyway, thankyou for helping me,
Giulia Menconi
