Porechop: a tool for finding adapters in Oxford Nanopore reads, trimming them
from the ends and splitting reads with internal adapters
Main options:
-i INPUT, --input INPUT
FASTA/FASTQ of input reads or a directory which will
be recursively searched for FASTQ files (required)
-o OUTPUT, --output OUTPUT
Filename for FASTA or FASTQ of trimmed reads (if not
set, trimmed reads will be printed to stdout)
--format {auto,fasta,fastq,fasta.gz,fastq.gz}
Output format for the reads - if auto, the format
will be chosen based on the output filename or the
input read format (default: auto)
-v VERBOSITY, --verbosity VERBOSITY
Level of progress information: 0 = none, 1 = some, 2
= lots, 3 = full - output will go to stdout if reads
are saved to a file and stderr if reads are printed
to stdout (default: 1)
-t THREADS, --threads THREADS
Number of threads to use for adapter alignment
(default: 16)
Barcode binning settings:
Control the binning of reads based on barcodes (i.e. barcode
demultiplexing)
-b BARCODE_DIR, --barcode_dir BARCODE_DIR
Reads will be binned based on their barcode and
saved to separate files in this directory
(incompatible with --output)
--barcode_threshold BARCODE_THRESHOLD
A read must have at least this percent identity to a
barcode to be binned (default: 75.0)
--barcode_diff BARCODE_DIFF
If the difference between a read's best barcode
identity and its second-best barcode identity is
less than this value, it will not be put in a
barcode bin (to exclude cases which are too close to
call) (default: 5.0)
--require_two_barcodes Reads will only be put in barcode bins if they have
a strong match for the barcode on both their start
and end (default: a read can be binned with a match
at its start or end)
--untrimmed Bin reads but do not trim them (default: trim the
reads)
--discard_unassigned Discard unassigned reads (instead of creating a
"none" bin) (default: False)
Adapter search settings:
Control how the program determines which adapter sets are present
--adapter_threshold ADAPTER_THRESHOLD
An adapter set has to have at least this percent
identity to be labelled as present and trimmed off
(0 to 100) (default: 90.0)
--check_reads CHECK_READS
This many reads will be aligned to all possible
adapters to determine which adapter sets are present
(default: 10000)
--scoring_scheme SCORING_SCHEME
Comma-delimited string of alignment scores: match,
mismatch, gap open, gap extend (default: 3,-6,-5,-2)
End adapter settings:
Control the trimming of adapters from read ends
--end_size END_SIZE The number of base pairs at each end of the read
which will be searched for adapter sequences
(default: 150)
--min_trim_size MIN_TRIM_SIZE
Adapter alignments smaller than this will be ignored
(default: 4)
--extra_end_trim EXTRA_END_TRIM
This many additional bases will be removed next to
adapters found at the ends of reads (default: 2)
--end_threshold END_THRESHOLD
Adapters at the ends of reads must have at least
this percent identity to be removed (0 to 100)
(default: 75.0)
Middle adapter settings:
Control the splitting of read from middle adapters
--no_split Skip splitting reads based on middle adapters
(default: split reads when an adapter is found in
the middle)
--discard_middle Reads with middle adapters will be discarded
(default: reads with middle adapters are split)
(required for reads to be used with Nanopolish, this
option is on by default when outputting reads into
barcode bins)
--middle_threshold MIDDLE_THRESHOLD
Adapters in the middle of reads must have at least
this percent identity to be found (0 to 100)
(default: 85.0)
--extra_middle_trim_good_side EXTRA_MIDDLE_TRIM_GOOD_SIDE
This many additional bases will be removed next to
middle adapters on their "good" side (default: 10)
--extra_middle_trim_bad_side EXTRA_MIDDLE_TRIM_BAD_SIDE
This many additional bases will be removed next to
middle adapters on their "bad" side (default: 100)
--min_split_read_size MIN_SPLIT_READ_SIZE
Post-split read pieces smaller than this many base
pairs will not be outputted (default: 1000)
