I was able to succeessfully remove adapters from my PE 150bp x 2 reads using, but I kept seeing that I had a long string of Gs in my R2 sequences (~ 0.1% of my R2 reads).

I reran the original fastq files with bbduk to remove the string of Gs, and this worked for most of my PE files except for one pair.

When I ran this trimmed set of PE reads through FastQC (after bbduk), I received an error that said:

Failed to process file EA_Pool-POW_1-1a_S28_L001_R1_CLEANEST.fastq Ran out of data in the middle of a fastq entry.  Your file is probably truncated

Has anyone encountered this issue before with output fastqs from bbduk?

Should I just not worry about the ~0.1% of GGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG kmers in my R2 reads?

Thank you!
