Missing regions in fly ideogram?

[nmorozovamathbio]

Hi Eric,

I have a question about fly genome (D. melanogaster) ideograms.

It looks like that chromosomes on ideograms have different length than in the NCBI assembly:

They look like that in Jupyter implementation 2R < X < 2L < 3L < 3R:

However, the lengths in the assembly are 2L < X < 2R < 3L < 3R

Moreover, some regions are not annotated when I try to annotate them on chromosomes, for example :

no mark for reg1 = {'name': 'reg1', 'chr': '2R', 'start': 4314169, 'stop': 4321055}

mark appears for the same coordinates for chr2L reg2 = {'name': 'reg2', 'chr': '2L', 'start': 4314169, 'stop': 4321055} :

Could it be that some regions are missing?

Hi Natalia, thanks for bringing this to my attention. It seems at least partly caused by an issue in the underlying data, like #189. I aim to fix this in the next release.

Thanks a lot!

This is resolved per #348, and the fix will be available in the next Ideogram.js release. Thanks again for the report!
