Custom adapters cannot be found when binning but can be found using trimming function

[v1tazhan9]

Hi! I input custom adapter using adapter.py, these adapters can be found if i use -o function for trimming

"30,139 / 32,299 reads had adapters trimmed from their end (2,444,748 bp removed)"

but when I use - b function to bin, and it says
"Error: no barcodes were found, so Porechop cannot perform barcode demultiplexing"
i try to set the threshold really really low just to try and get nothing, tried verbosity for debugging and nothing

here's a history:
% porechop -i /Users/vita/Desktop/GladLab/Nanopore_DEPC_data/R1_A_probed/fastq_pass/R1_A_probed.fastq -b /Users/vita/Desktop/GladLab/Nanopore_DEPC_data/porechop/bin --barcode_threshold 20 --barcode_diff 1 --verbosity 3

Looking for known adapter sets
