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
