It turns out that your artificial test is a bit too artificial. In order to display a coverage plot, Trackster converts reads in a BAM to BigWig using a two step process: (1) BAM to bedgraph; (2) bedgraph to bigwig Your super simple example generates an empty file in step 1 because your single read does not map to Araly1, and the tool used in step 2 (bedGraphToBigWig) fails with the error that you're seeing. This is a corner-case bug, and I've create a card for this so you can track its resolution: https://trello.com/c/kMFUNawL Best, J.

I'm having problems getting Trackster working on my own Galaxy instance, so I thought I would check on the usegalaxy public server.
However, I'm getting the same Trackster Error: needLargeMem: trying to allocate 0 bytes (limit: 100000000000) that was reported on this list in July, but there was no followup: http://user.list.galaxyproject.org/Trackster-Error-td4655737.html
My history is at https://usegalaxy.org/u/simon-guest/h/trackster-error
This is just an artificial test I made using a fragment of a reference genome, but I thought it should work OK.
Any clues?
