unable to view region in bam file about ribbon

[MariaNattestad]

Hi,
I have had the same problem, and from what I can tell it stems from attempting to load too much data from the bam file. The bam library probably doesn't know that it will exceed the available memory, and I have tried to preview the bam file or somehow prevent it from loading everything at once, but I can't find any ways to do this.
From the cancer genome I usually look at, it occurs in regions with more than about 800 reads.
Maybe in your viral genome the coverage is also very high. It may be possible to use Ribbon if you down-sample the bam file, but you can test with samtools to see how many reads it is trying to load to confirm that this is the problem first.

Thanks for your reply. I talked to @chmille4 about it too, since the iobio code is running under the hood for the BAM file loading. He said pretty much the same thing. I'll try downsampling the BAM because the genome is fairly small ( < 200kb) , but my coverage is ~3000x

Hi Maria - Yes, I downsampled the BAM and the 'aw,snap' error goes away. Thanks for your help!
