hgTracks object is missing from the response

[Gilderlanio S. de Araújo]

Hi, 

I am trying to use the UCSC Genome Browser, that works perfectly for some chromosome regions that I have queried. But for example, for the regions below I got the message "hgTracks object is missing from the response". is this a bug?

Chr 10

135314777

135435668

Chr 13

114888604

115039200

Hello Gilderlanio,

Thank you for using the UCSC Genome Browser and reporting your error message. I am assuming you are using the hg38 build since both the positions that you provided work on the hg19 build.

The end positions you are entering are larger than the length of the chromosome, but the error message doesn't explicitly tell you that. The chromosome size for chr10 on hg38 is 133,797,422 bases, but your start region for this chromosome is at 135,314,777, two million bases past the end of the chromosome.

We have updated this error message to now say:

Window out of range on chr10

If you are working with hg19 coordinates but would like to use the hg38 build, you can use our liftOver tool to convert coordinates between assemblies.

I hope this is helpful. If you have any further questions, please reply to gen...@soe.ucsc.edu.
