The Daubechies wavelet coefficients are 108 time steps long (instead of 216) because it makes use of the discrete wavelet transform. Using the handy pywavelets package we can fetch the filter coefficients for our favorite wavelet and use it as a convolution kernel in a series of convolution layers. In order to analyze the electrophysiological data at the population level, we designed the PopuAnalysis module.
