I ran the emboss program "palindrome" on the sequence K01964.
This sequence has an inverted repeat of length 11, occurring at 122-132
and 4672-4682. These inverted repeats have a mismatch at the first base
(the entire 11 bases are defined as inverted repeats for several reasons).
I noticed two problems when I ran palindrome on this sequence:
1)The "maximum length of palindrome" is actually the maximum length +1.
(To search for a specific palindrome length the maximum length must be
the minimum length +1).
2) When searching for a repeat of length 11 with at least one mismatch
in the above example, the true inverted repeats are not found. I
imagine that this is because the mismatch is on the edge, however there
is meaning for this type of hit.
