[Eeglablist] pop_resample() - potential bug?

[Andreas Widmann]

Entering

[p,q] = rat(250/500, 1e-12)

on the MATLAB command line results in

p = 1
q = 2

where p and q are exactly 1 and 2 (and other results would be surprising).

Please double-check that your EEG.srate is *exactly* 500 and that you have not overloaded the MATLAB built-in rat() function.

Best,
Andreas
