Does the downloaded dataset still require preprocessing

[xiewangyyds]

Hello, I am a beginner in the BCIC field and I am currently looking to reproduce your code. May I ask if we can start from here https://bnci-horizon-2020.eu/database/data-sets Do I need to perform any other preprocessing operations after downloading the dataset

Thank you for your interest in my work. I apologize for not always responding promptly to messages on GitHub. A simple way I usually access the BNCI dataset is by using the MOABB package. This package provides basic preprocessing and does not require any additional handling. Alternatively, you can directly use the filterbank function included in my code.
