- AlignIR has three search modes to assure that you will
quickly find the sequence you are looking for:

- Best Match searches find exactly the
sequence you enter, or something close to your sequence
if you set the match percentage below 100%.
- IUPAC Searches let you enter search
strings containing IUPAC ambiguity codes. Using an IUPAC
search,
AlignIR will also find sequences that are the same
as the sequence you enter except that an appropriate
IUPAC ambiguity
code has been inserted at some position.
- Regular Expression Searches let you
extend your search capabilities by adding expression
operators
to your search text. Expression operators can be "wild
card" characters, logical operators like "and" or "or",
and a variety of other operators that help you do things
like finding repeat sequences with any number of repeats.
