+# Like usearch, vsearch returns semi-global pairwise alignments,
+# ignoring terminal gaps
+
+# The alignment of:
+
+# primer query:   ACAGTGACATGGGGACGTAT
+# reference:       CAGTGACATGGGGACGTAT...
+
+# is:
+
+# Qry    2 + CAGTGACATGGGGACGTAT 20
+#            |||||||||||||||||||
+# Tgt    1 + CAGTGACATGGGGACGTAT 19
+
+# and not:
+
+# Qry    1 + ACAGTGACATGGGGACGTAT 20
+#             |||||||||||||||||||
+# Tgt    1 + -CAGTGACATGGGGACGTAT 19
+
+
+# alignment starts at position 2 for the query (ignore 5' gap)
