Where To Find Chromosome Band?

Question

[Shaojiang Cai]

Hi, I am working on some visualization project. I would like to find the chromosome band information such as:

chr1    0    2300000    p36.33    gneg
chr1    2300000    5400000    p36.32    gpos25
chr1    5400000    7200000    p36.31    gneg
chr1    7200000    9200000    p36.23    gpos25
chr1    9200000    12700000    p36.22    gneg
chr1    12700000    16200000    p36.21    gpos50

Where to find the band information for S.pombe and E.coli, etc?

Thanks. I can find hg19/hg18/mm8/mm9, but would like to find spombe and ecoli.

Sorry. Haven't read your last sentence.

I may be wrong, but my understanding of cytobands, is that they do not appear in prokaryotes so band information for E. coli is not available. While cytobands might appear in S. pombe, as far as I can tell the yeast community does not record them, instead using other karyotyping techniques (see here).
