**What it does**: this tool converts sequence alignments in BAM format into BED, BED12 or BEDPE format running the command "bamtobed" of bedtools. 

.. class:: warningmark

If you want a **BEDPE output**, your input has to be paired-end and sorted by read name.

.. class:: warningmark

About **score calculation** : the option "another tag" is disallowed with BEDPE output.

.. class:: warningmark

About the options **-split** and **-cigar** : -split is disallowed with edit-distance as a calculation for BED score. -cigar is not displayed with -splits, and disallowed with edit-distance as a calculation for BED score.

.. class:: infomark
