Okay, I need a small regexp to recognize e-values . I thought this one would suffice: (\d*e-\d+|0\.\d+) But apparently it only recognizes: e-126 2e-20 1e-09 0.001 0.004 0.015 And not: 0.23 0.90 Can anyone tell me why this is the case?

I used this one (for searching in an hmmsearch-output) and it worked for me. The range from 1 to 5 is a bit arbitrary though. (\d{1,5}\.?\d{0,5}e?[+-]?\d{0,5}) Esther. Sebastian Proost wrote:

with me they both work :-/ but... ALWAYS be careful when using the ' | ': actually it says in your regex: \d+ or 0 it does NOT refer to the previous chars only the one just in front of the pipe. if you group them with () then it says what you want to it to say. L. Sebastian Proost wrote:

Yeah, well... It's actually the perl regular expression matcher of PHP ... So I guess there might be some caveats that I'm not aware of . lieven sterck wrote:

alternatively, better use the char-class approach: with the [ ] eg. \d+[ (e-)|\. ]\d+ Michiel Van Bel wrote:
