**Description**

Flexbar is a program to preprocess sequencing data. It demultiplexes barcoded runs and removes adapter sequences. Further, basic read trimming and filtering options are provided. Flexbar increases mapping rates and improves genome and transcriptome assemblies. It supports next-generation sequencing data in fasta/q and csfasta/q format from Illumina, Roche 454, and the SOLiD platform. Flexbar is available on the project_ page.

.. _project: https://sourceforge.net/projects/flexbar

------

**Trim-end modes**

**Any:** longer part of read remains

**Left:** align before or at read end, right part remains

**Right:** align after or at read start, left part remains

**Left tail:** consider first n bases, see tail-length options

**Right tail:** use only last n bases of reads in alignment

------

**Documentation**

Further documentation is available on the `manual`__ wiki page and via the command line help screen.
