Python command-line tool for demultiplexing Oxford Nanopore reads from FASTQ files
options:
- -h, --help
-
show this help message and exit
- -V, --version
-
show program's version number and exit
- -l LOG, --log LOG
-
Print debug information
- --quiet
-
Don't print summary
General settings:
- -f FASTQ, --fastq FASTQ
-
Barcoded read file
- -b BARCODE_DIR, --barcode_dir BARCODE_DIR
-
If specified, qcat will demultiplex reads to this folder
- -o OUTPUT, --output OUTPUT
-
Output file trimmed reads will be written to (default: stdout).
- --min-score MIN_QUAL
-
Minimum barcode score. Barcode calls with a lower score will be discarded. Must be between 0 and 100. (default: 60)
- --detect-middle
-
Search for adapters in the whole read
- -t THREADS, --threads THREADS
-
Number of threads. Only works with in guppy mode
- --min-read-length MIN_LENGTH
-
Reads short than <min-read-length> after trimming will be discarded.
- --tsv
-
Prints a tsv file containing barcode information each read to stdout.
- --trim
-
Remove adapter and barcode sequences from reads.

RBK001,NBD114,DUAL} Sequencing kit. Specifying the correct kit will improve sensitivity and specificity and runtime (default: auto)
- --list-kits
-
List all supported kits
Demultiplexing modes:
- --guppy
-
Use Guppy's demultiplexing algorithm (default: false)
- --epi2me
-
Use EPI2ME's demultiplexing algorithm (default: true)
- --dual
-
Use dual barcoding algorithm
- --simple
-
Use simple demultiplexing algorithm. Only looks for barcodes, not for adapter sequences. Use only for testing purposes!
EPI2ME options (only valid with --epi2me):
- --no-batch
-
Don't use information from multiple reads for kit detection (default: false)
- --filter-barcodes
-
Filter rare barcode calls when run in batch mode
Simple options (only valid with --simple):
- --simple-barcodes SIMPLE_BARCODES
-
Use 12 (standard) or 96 (extended) barcodes for demultiplexing
