Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 9 new columns ({'units', 'description', 'sampling_frequency', 'status', 'status_description', 'low_cutoff', 'type', 'name', 'high_cutoff'}) and 12 missing columns ({'duration', 'idx', 'timeds', 'timemeg', 'phonemeidx', 'wavile', 'wordidx', 'kind', 'sentenceidx', 'timechapter', 'segment', 'timesentence'}).
This happened while the csv dataset builder was generating data using
hf://datasets/pnpl/LibriBrain/metadata/channels.tsv (at revision 3649c4738806f4abb340502b9e73eb65e8adcab8)
Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

This repository contains the LibriBrain data organised by book: MEG recordings (.h5), event annotations (.tsv), and the audiobook stimulus audio (.wav).
Data are organised into seven top-level directories:
Sherlock1/Sherlock2/Sherlock7/Each Sherlock{i} directory contains:
Sherlock{i}/derivatives/events/ — event annotation files (.tsv)Sherlock{i}/derivatives/serialised/ — MEG recordings (.h5)Sherlock{i}/stimuli/audio/ — stimulus audio (.wav)The spoken-audio stimuli are derived from LibriVox public-domain recordings of the first seven Sherlock Holmes books (recording versions linked below). The stimuli are provided in this repository as WAV files converted from the LibriVox downloads.
The WAV files in this repository are:
Example conversion command (SoX):
sox "INPUT_FROM_LIBRIVOX.mp3" -c 1 -r 22050 -b 16 "OUTPUT.wav"
