MED example dataset (no data, only headers) #469
base: master
Are you sure you want to change the base?

@MEDFormat you will have to rename the folders to comply with the BIDS data strcuture. |
What does that mean? MED & MEF (currently accepted by BIDS) require certain naming conventions.

please check any of the other iEEG datasets in this repo and see how the files are named and try top match this. for example
Given that MED has files listed under a folder I think you may have to follow what is done with MEG for

Can you point me to the MEF 3.0 example? I cannot find it, but MED will be almost identical. |

I think your dataset should be structured like this

but you are going to require some extra json files |
@MEDFormat @Remi-Gau I've copied a pared down version of Making some additional changes to adjust validator behavior, given that we aren't targeting the legacy validator and the schema changes havn't been merged yet. |

maybe we should mention in the README that this dataset was mostly copied and adapted from another example: in case someone is looking for the 'real' BIDS dataset for this, otherwise they may think that we already have one that exist in the wild that they could have a look at.
