To do

• Fix channel location: Only place channel location in .set file, do not add electrode file
• Fix channel location: Coordinates are wrong (too shrinked). fix
• Events.json at the root not seen
• Dung to clean
• Kay says events in .set not consistent enough with events.tsv files (I have checked and they are)
• Dataset description, add more information

Kay

Beyond what we discussed, there were a large number of errors in the json and events.tsv files themselves. For example the "stim_file" column in the events.tsv was called "stim_type" in the json. Similarly the "value" column in the events.tsv was called "type" in the json. The trial_type values listed in the json file did not correspond to the values in the trial_type column values in the events.tsv file. This is why we want people to generate the json template from the event files. etc. etc. There was also an annotation in the JSON for a "correct" column which doesn't exist in the event files. None of the annotations included an event type tag.

I have attached a finished JSON file which would go on the top level of your dataset directory. There is one thing that I didn't understand. The correct response was tagged with a key Release, whereas the incorrect response was tagged with a Hold-down. There was no explanation in the description. These two annotations will probably have to be modified.

I also included a summary of what appeared in your events. You have a total of 52662 events in 350 event files.
