filtlong1
Quality filtering tool for nanopore and pacbio reads
Usage
filtlong OPTIONS
[input_reads]
Options
positional arguments:
- input_reads
-
input long reads to be filtered
optional arguments:
-
output thresholds:
-
-t[int], --target_bases [int] -
keep only the best reads up to this many total bases
-
-p[float], --keep_percent [float] -
keep only this percentage of the best reads (measured by bases)
-
--min_length [int] -
minimum length threshold
-
--min_mean_q [float] -
minimum mean quality threshold
-
--min_window_q [float] -
minimum window quality threshold
-
external references (if provided, read quality will be determined using these instead of from the Phred scores):
-
-a[file], --assembly [file] -
reference assembly in FASTA format
-
-1[file], --illumina_1 [file] -
reference Illumina reads in FASTQ format
-
-2[file], --illumina_2 [file] -
reference Illumina reads in FASTQ format
-
score weights (control the relative contribution of each score to the final read score):
-
--length_weight [float] -
weight given to the length score (default: 1)
-
--mean_q_weight [float] -
weight given to the mean quality score (default: 1)
-
--window_q_weight [float] -
weight given to the window quality score (default: 1)
-
read manipulation:
-
--trim -
trim non-k-mer-matching bases from start/end of reads
-
--split [split] -
split reads at this many (or more) consecutive non-k-mer-matching bases
-
other:
-
--window_size [int] -
size of sliding window used when measuring window quality (default: 250)
-
--verbose -
verbose output to stderr with info for each read
-
--version -
display the program version and quit
-
-h, --help -
display this help menu
