I have EEG data from 25 channels and I wish to combine the STFT spectrograms from those 25 channels into one single image for feeding the data into a CNN. I tried using imagesc to obtain a single spectrogram but when I feed the resulting dataset into the CNN, it gives a very miniscule accuracy, so I wanted to know whether there is some other way of combining the data from the different channels as well.

Hi Atharv,
I understand that you want to train CNN using EEG data from 25 channels. You can use a pretrained CNN(for example: Googlenet) by replacing the imageInputLayer, first convolutionLayer to match the input image channel dimension & convolution filter dimensions. You can then fine tune hyperparameters for better accuracy.
Refer to the below link for a similar query.
I hope it helps.
