the hg19 chromosome size in ncbi is different with UCSC?

[tintin306]

NCBI: http://www.ncbi.nlm.nih.gov/projects...ta/index.shtml
UCSC : http://www.ncrna.org/glocal/cgi-bin/...chromInfoPage=
or fetched by program "fetchChromSizes"

I tried to run wigtoBigwig, but it reported : chromosome chr17 has 81195210 bases, but item ends at 81195220

The original wiggle file is generated by MACS (the chip-seq peak calling algorithm).

Thanks,

Hi Tim

The differences in size is because you are seen different genome reference. I mean, In NCBI, the latest reference genome is GRCh37.p7, but if you see the GRCh37.p5 the length of all chromosomes are equal to the UCSC genome reference,

Hope this can help you
