+**What it does**
+
+Accepts a combination of single BAM and associated VCF files (or associated collections of each) to produce a VCF file for each
+combination whose positions with no coverage are represented as "N".  These outputs are restricted to SNPs and those regions
+along the reference with no coverage.
+
+A metrics file is produced for each combination which provides the number of good SNPs, the average coverage and the genome
+coverage percentage.
+
+**Required Options**
+
+ * **Choose the category of the files to be analyzed** - select "Single files" or "Collections of files", then select the appropriate history items (single BAM and VCF files or collections of BAM and VCF files) based on the selected option.
+ * **Choose the source for the reference genome** - select "locally cached" if the reference associated with the BAM and VCF files is available within the Galaxy environment or "from history" to select the reference from the current history.
