Converting matlab code to python

Question

Okay so I have a datafile from an EEG scan (a binary file, data.eeg), and in matlab the code to read the file and plot a section of the data goes like this:

Answer 1

As discussed in the comments by yourself and @JoeKington, this should work (I removed the input stuff for testing)

import numpy as np

sample_rate = 400
Nyquist = sample_rate/2.0
fneeg = 'data.eeg'
t = 10 
ch = 32
le = t*sample_rate
EEG = np.fromfile(fneeg, 'int16').reshape(ch, le, order='F')

Without the reshape, you get:

In [45]: EEG
Out[45]: array([ -39,  -25,  -22, ..., -168, -586,  -46], dtype=int16)

In [46]: EEG.shape
Out[46]: (128000,)

With reshaping:

In [47]: EEG.reshape(ch, le, order='F')
Out[47]: 
array([[ -39,  -37,  -12, ...,    5,   19,   21],
       [ -25,  -20,    7, ...,   20,   36,   36],
       [ -22,  -20,    0, ...,   18,   34,   36],
       ..., 
       [ 104,  164,   44, ...,   60,  -67, -168],
       [ 531,  582,   88, ...,   29, -420, -586],
       [ -60,  -63,  -92, ...,  -17,  -44,  -46]], dtype=int16)

In [48]: EEG.reshape(ch, le, order='F').shape
Out[48]: (32, 4000)
