TAL effector nucleases
Pattern search for talen binding and cleavage sites

This tool identifies TAL effector nuclease binding and cleavage sites in sequences. FASTA sequence format is accepted as input. The input can contain several sequences in FASTA format. Each sequence must have a unique identifier. Special characters as input are not accepted.

The option can be used to select between a search with a stringent pattern or a rather relaxed pattern. The search is done with one of the following patterns:
Stringency 'relaxed':        T.{13,15}[spacer].{13,15}A
Stringency 'stringent':        T.{15}[spacer].{15}A
The length of the [spacer] between the binding sites is variabel and can be selected by the user.
A T at the beginning and an A at the sequence end is mandatory.
