@Pavel_Prado , I hope that you are doing well. This seems like a very promising dataset, and I appreciate your diligence in uploading it. I am currently trying to make sure that I can open all of the EEG files. However, different subjects seem to have both .set and .fdt, only .set files, or only .fdt files. Unfortunately, I can't seem to open data for the subjects that only have .fdt files in Python (e.g., s6_sub-100011_rs_eeg.fdt). I have tried using scipy.io.loadmat, h5py, and mne. It is also possible that I have running into a versioning issue with the Python packages. Do you have any suggestions on how to open data for those subjects that only have .fdt files? Thank you, Charles Ellis
