.. class:: warningmark

  This tool requires sequencing reads in BAM format. If your reads are in SAM format, use the SAM-to-BAM tool under NGS: SAMTools.

.. class:: warningmark

For paired-end MNase data, read centers are approximated by using the center of the read. For single-end data, the estimated mononucleosome fragment length must be specified, which will be used to offset reads from the + and - strands.
