DataCloneError when loading source

[broodjeaap]

I'm trying to load a bam/bam.bai file through the sources parameter. The files are located in the same directory/location on the server and according to the developer console, are being downloaded. But after its done, the response is 'null'. It automatically tries again a couple of times with the same result, giving the "DataCloneError" sometimes.

Are there any requirements for this kind of setup to work?

Sorry to hear you're having trouble.

From the error message, it seems as though there may be a problem with communication between the main Biodalliance code and a Web Worker that recent versions of Biodalliance use to accelerate BAM (and bigBed/Wig) parsing. However, beyond that I don't have a lot to go on.

• What version of Biodalliance are you using?
• Which web browser are you using, and have you tried a different one?
• Might it be possible to see the track configuration you're using?

One other thing that might be worth trying is to add:

             maxWorkers: 0

to your top-level Biodalliance configuration, which will disable the Web Worker system entirely. Even if this doesn't fix your problem, it's possible that it'll lead to a more informative error message.

Thank you for the quick response.

To answer you questions: I'm using biodalliance 0.13 I've tried multiple webbrowsers (Firefox, Chrome and Opera) I've also tried different tracks, which work when adding them through the 'browse' funcionality.

Adding the "maxWorkers: 0" will be the next thing I will try, the more informative error message will probably help a lot.

Thank again for the (quick) response.

Not heard any more so closing for now.
