**What is does**

BAMTools is a collection of utilities for manipulation on BAM files. It is based on BAMtools suite of tools by Derek Barnett (https://github.com/pezmaster31/bamtools).
This Galaxy implementation of BAMTools utilities includes seven utilities - Convert, Count, Coverage, Header, Merge, Random, and Revert - decsribed in detail below.

-----

**Convert**

Converts BAM dataset(s) into BED, FASTA, FASTQ, JSON, Pileup, SAM, or YAML formats. Note that the conversion to the pileup format requires providing a reference sequence either
cashed at this Galaxy instance, or provided by you as a FASTA dataset from History.

-----

**Count**

Counts a number of alignments in a BAM dataset(s).

-----

**Coverage**

Prints per-base coverage for a BAM dataset.

-----

**Header**

Prints header from a BAM dataset(s).

------

**Merge**

Merges multiple BAM datasets into a single one. Obviously, you need to select multiple BAMs as input, which is done by pressing the "**Add new BAM dataset(s) to filter**" button.

------

**Random**

Grabs a specified number of random lines from BAM dataset(s).

------

**Revert**

Removes duplicate marks and restores original (non-recalibrated) base qualities.
