Hello @Pardal_Oblackovy !
This suggests that you may have some corrupted read around line 17 on sample X13T forward reads. In this post a similar issue is addressed. Could you please run:
# If your FASTQ file is compressed
zcat path/to/fastq.gz | head -n 30
# Else
head path/to/fastq -n 30
and share the output with us? Maybe we can visually spot the issue ![]()
Best,
Sergio
