Hi Wouter,
I tried this kinda thing for the regex strings:
regex =
re.compile('\\t+([-+]?\d+\.?\d*)\\t+([-+]?\d+\.?\d*)\\t+([-+]?\d+\.?\d*)\\t+([-+]?\d+\.?\d*)\\t+')
I'd recommend:
re.compile('[ \\t]+([-+]?\d+\.?\d*){4}[ \\t]+')
The {4} means the same expression has to match exactly 4 times. This
makes the expression a bit more readable I think.
Otherwise, I would also recommend what Nathan's suggesting.
HTH,
Wouter
Didn't help (though testing the string in pythonregex.com
<http://pythonregex.com> does show results).
If I did it wrong I'd love to know. Any other ideas welcome too.
Thanks!

Hi Wouter,
thanks. That's something I haven't tried.
I'll have a look.

Any chance you can have another look?
Your regexps look very strict. I would suggest to be more
permissive in the amount and kind of whitespacing you allow
between numbers.
I would suggest:
[:blank:]+ instead of \t
Or if the Python regexps don't support he POSIX character
classes, just [ \t]+.
It's entirely possible that you're getting spaces in the pasted
data instead of the tabs read from file.
