-Uses SAMTools_' pileup command to produce a file in the pileup format based on the provided BAM file. +Uses SAMTools_' pileup command to produce a pileup dataset from a provided BAM dataset. It generated two types of pileup datasets depending on chosen 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.
