Class EEPBin
source code
Read-access to binary EEP files.
EEP files are used by eeprobe a software for analysing even-related
potentials (ERP), which was developed at the Max-Planck Institute for
Cognitive Neuroscience in Leipzig, Germany.

EEP files consist of a plain text header and a binary data block in a
single file. The header starts with a line of the form
';%d %d %d %g %g' % (Nchannels, Nsamples, Ntrials, t0, dt)
where Nchannels, Nsamples, Ntrials are the numbers of channels, samples
per trial and trials respectively. t0 is the time of the first sample
of a trial relative to the stimulus onset and dt is the sampling interval.
The binary data block consists of single precision floats arranged in the
following way:
<trial1,channel1,sample1>,<trial1,channel1,sample2>,...
<trial1,channel2,sample1>,<trial1,channel2,sample2>,...
.
<trial2,channel1,sample1>,<trial2,channel1,sample2>,...
<trial2,channel2,sample1>,<trial2,channel2,sample2>,...
