is true, then the maximum value becomes
+ * zero, i.e. all values are subtracted from the maximum. This is consistent
+ * with converting an identity similarity score to a distance score - the most
+ * similar (identity) corresponds to zero distance. However note that the

+ * For example a range of 10-40 would become 30-0, which would reverse a
+ * second time to 0-30. Also note that a general similarity measure (such as
+ * BLOSUM) may give different 'identity' scores for different sequences, so
+ * they cannot all convert to zero distance.

is false, then the values are reflected
