+
+   **What it does**
+
+The tool transforms the read-centered information in the aligned reads input
+datasets into position-centered information including variant call statistics
+(using samtools mpileup and bcftools internally).
+
+**It produces a BCF file that serves as the basis for all further variant
+analyses with MiModD**.
+
+-----
+
+**Notes on Advanced Settings:**
+
+**MD5 checksums**
+
+By default, the tool will check whether the input BAM dataset(s) provide(s) MD5
+checksums for the reference genome contig/chromosome sequences used during read
+alignment (e.g., the *MiModD Read Alignment* tool stores these in the BAM file
+header). If it finds MD5 sums for all sequences, it will compare them to the
+checksums of the reference genome sequences used in the current tool run and
+abort with an error message if there is a discrepancy between them. If it finds
+contigs/chromosomes with matching checksum, but different names in the aligned
+reads dataset(s) and the reference genome dataset, it will use the name from
+the reference genome in its output.
+
+This behavior has two benefits:
+
+1) It protects from accidental variant calling against a wrong reference genome
+(*i.e.*, a different one than that used during the alignment step), which would
+result in wrong calls. This is the primary reason why we recommend to leave the
+check activated.
+
+2) It provides an opportunity to change sequence names between aligned reads
+files and variant call files by providing a reference genome file with altered
+sequence names (but identical sequence data).
+
+Since there may be rare cases where you *really* want to align against a
+reference genome with different checksums (e.g., you may have edited the
+reference sequence based on the alignment results), the check can be turned
+off, but only do this if you know *exactly* why.
+
+
+**Average sample depth cap limit**
+
+For each of a total of ``M`` BAM input datasets, the tool will only pile up a
+maximum number of reads ``N`` per position to avoid excessive memory usage with
+very large numbers of samples sequenced at high coverage.
+N will be calculated as the maximum of ``8000/M`` and ``DEPTH*S``, where ``S``
+is the maximum number of samples found in a single input dataset and ``DEPTH``
+is the *average sample depth cap limit* specified in the tool form.
+
+This parameter, thus sets the average depth of the pile-up per sample that is
+guaranteed to be used even when there is a very large number of samples. As can
+be seen from the formula above, however, it will rarely become relevant for any
+regular-size analysis.
