[Eeglablist] import BDF file data one channel at a time

[Ryan Canolty]

Hello all,

In my greed to gather data, I generated a massive (~2 
gigabytes) .bdf file (Biosemi Data Format) which is 
causing me difficulty.  I recorded 72 channels at 2048 Hz 
sampling rate for 80 min or so.  While I know now that 
this is not a good idea, I'd still like to use the data. 
 The only program I can get to open it is EEGLAB, and even 
then only if I select chunks of 100 sec or so, otherwise I 
get an out of memory error.

My question:  is anyone aware of a way to read in one or 
two channels (ideally an EEG channel and the event 
channel) at a time into EEGLAB, rather than reading all 
channels at once?  That way I could look at large segments 
of the continuous EEG separately for each channel rather 
than short snippets of all 72 channels.

Thanks,
Ryan
