116 **What it does**
117
118 Uses SAMTools_' pileup command to produce a pileup dataset from a provided BAM dataset. It generates two types of pileup datasets depending on the specified options. If *Call consensus according to MAQ model?* option is set to **No**, the tool produces simple pileup. If the option is set to **Yes**, a ten column pileup dataset with consensus is generated. Both types of datasets are briefly summarized below.

124 **Types of pileup datasets**
125
126 The description of pileup format below is largely based on information that can be found on SAMTools Pileup_ documentation page. The 6- and 10-column variants are described below.

150 **Ten column pileup**
151
152 The `ten-column` (consensus_) pileup incorporates additional consensus information generated with *-c* option of *samtools pileup* command::
