I have 2 minutes of filtered data that needs to be segmented into 20msec intervals, how would I go about doing that? It was collected at 2048 Hz and there is a total of 245762 data points.

One option is the Signal Processing Toolbox buffer function.

It uses samples as one of its arguments, however that is straightforward to calculate:

Fs = 2048;                                              % Sampling Frequency (samples/sec)
segment = 0.02;                                         % Segments (20 ms)
Samples = round(Fs * segment);                          % Sample Length
