why,there

return (data.shape[1]-t*_SIZE_WINDOW_SPECTOGRAM)*-1

not

return (data.shape[1]-(t * movement+_SIZE_WINDOW_SPECTOGRAM))*-1

Actually I have some questions about your code:
1- In the training why did you choose that it be be for each patient apart I mean why didn't you collect the spectrograms for all patients and use it as input for CNN. .
2- How could I know the number of the training data used?

in DataserToSpectogram.py line 205
if (signalsBlock.shape[0] == 50):
saveSignalsOnDisk(signalsBlock, nSpectogram)

What does 50 mean, is it 50 times of 30 seconds sampling, or is it something else that I don't understand, please forgive me for being a beginner. Thank you very much for your reply

as for the result of codes, is it normal about chb05:sens=77,FPR=2.8;CHB19:sens=79,fpr=4?The result I got was not good,FPR is very far from zero.May I know your final results？thanks！！

I got this error even i put a path in the txt file

while running this code in google colab I am getting this error.

It takes me very long, >20 minutes for one epoch on GPU, is that normal?

Thanks,

训练19号病人损失为nan，前边的没问题，不知道是什么问题

What does the "real preictal" mean? I didn't find anything about it in the paper.When you train the CNN,what data will be used? preictal data or real preictal data ?I am really confused. Thank you

Can you please explain why you subtract (30 + 3) minutes at the referenced line? I thought that with SOP = 30 min and SPH = 3 min, we only subtract 3 minutes from the start time of the seizure onset?

hi
Why don't consider all 13 patients?
and
what are the threshold?

Hello @ritwikmishra ,
Thank you very much for providing such excellent code, I have a question to ask you .
I check the spectrogram generated in the first part of the code and get ”shape: (50, 21, 59, 114)“, what should I do to make the shape generate three-dimensional ？I would be grateful if you could provide some suggestions and look forward to receiving your reply .
