NAME

ABYSS - assemble short reads into contigs

SYNOPSIS

ABYSS [ OPTION]... FILE...

DESCRIPTION

Assemble all input files, FILE, which may be in FASTA, FASTQ, qseq, export, SRA, SAM or BAM format and may be compressed with gz, bz2 or xz and may be tarred.
 
Users wishing to run a full assembly with ABySS are recommended to use abyss-pe as their entry point rather than the ABYSS program. abyss-pe is a Makefile that coordinates many of the ABySS tools (including ABYSS) in order to run the full ABySS assembly pipeline. abyss-pe is capable of doing many things that ABYSS is not, such as leveraging the distance information provided by paired end reads and mate pair reads.
--chastity
discard unchaste reads [default]
--no-chastity
do not discard unchaste reads
--trim-masked
trim masked bases from the ends of reads [default]
--no-trim-masked
do not trim masked bases from the ends of reads
-q, --trim-quality=THRESHOLD
trim bases from the ends of reads whose quality is less than the threshold
-Q, --mask-quality=THRESHOLD
mask all bases in reads whose quality is less than the threshold
--standard-quality
zero quality is `!' (33)
 
default for FASTQ and SAM files
--illumina-quality
zero quality is `@' (64)
 
default for qseq and export files
-o, --out=FILE
write the contigs to FILE
-k, --kmer=KMER_SIZE
k-mer size
-t, --trim-length=TRIM_LENGTH
maximum length of dangling edges to trim
-c, --coverage=COVERAGE
remove contigs with mean k-mer coverage less than this threshold
-b, --bubbles=N
pop bubbles shorter than N bp (default: 3*k).
-b0, --no-bubbles
do not pop bubbles
-e, --erode=COVERAGE
erode bases at the ends of blunt contigs with coverage less than this threshold
-E, --erode-strand=COVERAGE
erode bases at the ends of blunt contigs with coverage less than this threshold on either strand
--coverage-hist=FILE
record the k-mer coverage histogram in FILE
-g, --graph=FILE
generate a graph in dot format
-s, --snp=FILE
record popped bubbles in FILE
