Hard to use

[O-Memis]

I investigated most of the links. Unfortunately, many of them are not useful, or not easy to use caused by several reasons.

1- Some broken or unable to access links
2- Lack of documentation. Lack of information about how to actually use the files. From which file I can access the data and labels? (especially in Openneuro formats)
3- Some of are outdated (especially UCI and Physionet)
4- Some of them are not used in an article yet, messy and lack of documentation
5- Not labeled yet (for those shared in terms of classification tasks)
6- Needs institutional access or approval (many of the clinical ones)
7- Just for practicing ones, not scientific (Kaggle).

I only find these two links as helpful : Predict and NEMAR however they also need documentations about the file usage.
By "file usage / documentation" what I mean is, the information of how to access the signals and labels, which file is what.

Researching by open-access articles seems like only solution to find an appropriate EEG classification dataset, I guess.
