I got a bam file and upload to the Galaxy.  When I convert it into bigwig, it gives me that message:1 is not found in chromosome sizes file.

Is there somebody can help me with that?

Thank you in advance.

Sounds like a mismatch between between chromosome names, where your bam has e.g. "1", but the dbkey/genome build uses "chr1".

Dear Daniel,

I have a question regarding the IGV and bigwig conversion that maybe you can help me. I am trying to convert a .bam file to bigwig with mouse genome (mm10) to visualize the reads and I am getting this error:

hashMustFindVal: 'GL456210.1' not found

and this is my command:

wigToBigWig  -clip mm10.chrom.sizes ./

I already found out that I need to convert the chromosome Ids to UCSC. I want to know is this common to convert the IDs from ENSEMBLE to UCSC for bigwig conversion? Do you have any idea about it?

Many Thanks in advance,
