[Mne_analysis] CSP components selection

hi,

setting N=4 should give you the first 2 and the last 2. Feature space
will then be 4 dimensional.

see how we do it here:

Normally, if we give N=2, then we select the first two and last two spatial filters from the CSP matrix to create our feature vector. When we did the same thing in MNE python, it is only selecting the two components. Can you advise how to handle this?
