I'm working with Illumina Miseq data. After BAM to fastq extraction I run fastqc to generate reports. With many of my samples I see two different sequence lengths as shown in the picture below:
Also want to add that if I see this in the sequence length distribution, it also means the sequence composition will be skewed:
Any idea what is causing this?
Single End Data
Adapters are removed off the sequencer
Thanks!
