Description:

The FASTX-Toolkit is a collection of command line tools for
Short-Reads FASTA/FASTQ files preprocessing.

Next-Generation sequencing machines usually produce FASTA or FASTQ
files, containing multiple short-reads sequences (possibly with
quality information).

The main processing of such FASTA/FASTQ files is mapping (aka
aligning) the sequences to reference genomes or other databases using
specialized programs. Example of such mapping programs are: Blat,
SHRiMP, LastZ, MAQ and many many others.

However, It is sometimes more productive to preprocess the FASTA/FASTQ
files before mapping the sequences to the genome - manipulating the
sequences to produce better mapping results.

The FASTX-Toolkit tools perform some of these preprocessing tasks.
