Guppy

Q: Why does guppy_barcoder fail to run on GPU nodes when the --detect_mid_strand_barcodes option is used?
     Error: "Exception thrown in Barcoder worker thread: Too many sequences for GPU threads to contain! Will continue with next input file."
A: This is a known bug in guppy_barcoder. To workaround the issue, explicitly specify the barcoding kit names (--barcode_kits) along with the --detect_mid_strand_barcodes option.
      eg: guppy_barcoder -i /data/guppy/abc -s out/ --trim_barcodes --detect_mid_strand_barcodes -x auto --barcode_kits "SQK-RBK004"
