Hi all, I used Kraken minion(version 15-065) to infer 3' adapter sequence but it output something that not consistent with the example output in manual.

My output

$ minion search-adapter -i rep1.R2.fastq.gz 
[minion] reading reads
.................................................  1
.................................................  2
[minion] set workspace to size 34854
[minion] connected component analysis
[minion] building consensus sequences
have 50

Standard output

$ minion search-adapter -i data.fq.gz -adapter <SEQUENCE>
criterion=sequence-density
sequence-density=25.68
sequence-density-rank=1
fanout-score=21.54
fanout-score-rank=9
prefix-density=49.06
prefix-fanout=21.5
sequence=TCGTATGCCGTCTTCTGCTTG

I'm wondering it's my fastq file problem or minion problem.

Many thanks!
