lordFAST: sensitive and Fast Alignment Search Tool for LOng noisy Read sequencing Data

lordFAST is a sensitive tool for mapping long reads with high error rates.
lordFAST is specially designed for aligning reads from PacBio sequencing technology but provides the user the ability to change alignment parameters depending on the reads and application.

How to install?

Build Status

Requirements

  • GCC ≥ 4.4.7
  • zlib

Using conda

lordFast can be installed using conda package manager via bioconda channel:

  1. $ conda install -c bioconda lordfast

From source code

In order to build lordFAST, please download the latest release from https://github.com/vpc-ccg/lordfast/releases or alternatively clone the repository by running the following command:

  1. $ git clone https://github.com/vpc-ccg/lordfast.git

Now the code can be compiled easily by running make command line which builds the binary file lordfast.

  1. $ cd lordfast
  2. $ make

How to run?

SYNOPSIS

  1. lordfast --index FILE [OPTIONS]
  2. lordfast --search FILE --seq FILE [OPTIONS]

OPTIONS

Run lordfast -h or man ./HELP.man to see available options.

Indexing options

  1. -I, --index STR
  2.     Path to the reference genome file in FASTA format which is supposed to be indexed. [required]

Mapping options

  1. -S, --search STR
  2.     Path to the reference genome file in FASTA format. [required]
  4. -s, --seq STR
  5.     Path to the file containing read sequences in FASTA/FASTQ format. [required]
  7. -o, --out STR
  8.     Write output to STR file rather than standard output. [stdout]
  10. -t, --threads INT
  11.     Use INT number of CPU cores. Pass 0 to use all the available cores. [1]

Advanced options

  1. -k, --minAnchorLen INT
  2.     Minimum required length of anchors to be considered. [14]
  4. -n, --numMap INT
  5.     Perform alignment for at most INT candidates. [10]
  7. -l, --minReadLen INT
  8.     Do not try to map any read shorter than INT bp and report them as unmapped. [1000]
  10. -c, --anchorCount INT
  11.     Consider INT anchoring positions on the long read. [1000]
  13. -m, --maxRefHit INT
  14.     Ignore anchoring positions with more than INT reference hits. [1000]
  16. -R, --readGroup STR
  17.     SAM read group line in a format like '@RG\tID:foo\tSM:bar'. []
  19. -a, --chainAlg INT
  20.     Chaining algorithm to use. Options are "dp-n2" and "clasp". [dp-n2]
  22. --noSamHeader
  23.     Do not print sam header in the output.

Other options

  1. -h, --help
  2.     Prints this help file.
  4. -v, --version
  5.     Prints the version of software.

EXAMPLES

Indexing reference genome:

  1. $ ./lordfast --index refgen.fasta

Mapping to the reference genome:

  1. $ ./lordfast --search refgen.fa --seq reads.fastq > map.sam
  2. $ ./lordfast --search refgen.fa --seq reads.fastq --threads 4 > map.sam
