Patterns/Motifs Repository

[alphaplanet]

Hi All,

I am new to this area. I am a researcher working on fast pattern searching in general scenarios (e.g., regex in string matching).

I am curious about the "regex" (pattern/motif) in bioinformatics. Can anyone help point out some repository where I can see some "regex" instances (used by people in real cases)?

So that I can get a sense how complex they are and the possibility to apply our techniques.

Thank you!
