WashU Browser New Version - Local Tracks Not Working for Some File Formats

[WANGchuang715]

I am currently using the new version of WashU Epigenome Browser and have encountered an issue with local tracks. It seems that only bigWig files can be directly loaded and used as local tracks. Other file formats, such as bedGraph, etc., are not loading properly.

new TrackModel({
    type: "bedGraph",
    name: "Capan-1.loop_bedgraph",
    url: "/browser/hg19/Capan-1_compartment.gz"
}),


    Error fetching data for track model type bedgraph: Error: Failed to fetch fetching /browser/hg19/Capan-1_compartment.gz

Thank you for finding the bug, the issue should be fixed once the new version is live.

I tried to upload HiChIP tracks in the "WashU.bed.gz" format and I nothing shows up. I try with the bedpe created for IGV and see what I used to see in older version of the browser

Hi @clolalan7 did you upload both .gz and .tbi together when you were trying?
