Question

[alwayshope]

Dear guys,

Below is the ATAC seq counts by featureCounts, Is it good or not so good? As the assigned are much less than unassigned...

Thanks a lot!

Unassigned_Singleton    0
Unassigned_MappingQuality       0
Unassigned_Chimera      0
Unassigned_FragmentLength       0
Unassigned_Duplicate    0

I've seen better, lets say it like this. Lots of unassigned reads, can indicate lots of noise. Check on a genome browser how data look, then you know.
