+
+**What it does**
+
+This is for processing duplex sequencing data. It does a multiple sequence alignment on each (single-stranded) family of reads.
+
+-----
+
+**Input**
+
+This expects the output format of the "Make families" tool.
+
+-----
+
+**Output**
+
+The output is a tabular file where each line corresponds to a (single) read.
+
+The columns are::
+
+  1: barcode (both tags)
+  2: tag order in barcode ("ab" or "ba")
+  3: read mate ("1" or "2")
+  4: read name
+  5: read sequence, aligned ("-" for gaps)
+  6: read quality scores, aligned (" " for gaps)
+
+-----
+
+**Alignments**
+
+The alignments are done using MAFFT, specifically the command
+::
+
+  $ mafft --nuc --quiet family.fa &gt; family.aligned.fa
