Hey thanks!, do you know why is there in `hgdownload.cse.ucsc.edu/goldenPath/hg38/database/` also the file `cytoBandIdeo.txt.gz`? I checked, and it has exactly the same info as `cytoBand.txt.gz`. BTW: do you know what the fourth column in `cytoBand.txt.gz` means? It has values like: `gneg`, `gpos25`, `gpos50`, `gpos100`, `acen`, etc..

<p>I am looking for a database that would keep track of  human cytogenetic regions and genomic coordinates per genome assembly. I had expected the Genome Reference Consortium to have it, or Ensembl, or NCBI, but I could not find it. </p>

<p>Is there a place with a translation table between human cytogenetic regions and genomic coordinates?</p>

<p>After benn's answer I found that you can also get this information from Ensembl's REST API: <a href="https://rest.ensembl.org/info/assembly/homo_sapiens?content-type=application/json&amp;bands=1" rel="nofollow noreferrer">https://rest.ensembl.org/info/assembly/homo_sapiens?content-type=application/json&amp;bands=1</a>.</p>

<p>I have transformed the data provided by Ensembl and generated a CSV file with the cytogenetic regions:</p>

Do you look for a database a paper with a table or what? To which genome should these genomic coordinates be from?

I am looking for a database that would keep track of human cytogenetic regions and genomic coordinates per genome assembly. I had expected the Genome Reference Consortium to have it, or Ensembl, or NCBI, but I could not find it.

Is there a place with a translation table between human cytogenetic regions and genomic coordinates?
