Chisco

# Chisco Dataset

This dataset is a Chinese imagined speech dataset with five participants, identified as sub-01 to sub-05. The dataset includes raw data and preprocessed data in both fif and pkl formats. Information also can be found in https://github.com/zhangzihan-is-good/Chisco

## Supplementary Information

The initial dataset release encompassed data from three participants (sub-01 to sub-03) as detailed in related Chisco publications. Subsequently, data from two additional subjects (sub-04 and sub-05) were incorporated. During the interval between the original dataset release and the addition of the new data, the BIDS protocol underwent updates. To preserve the integrity of the data processing code presented in our publications, the supplementary data continue to adhere to the previous version of the BIDS protocol. Consequently, the BIDS validator on our website may report errors; however, these do not compromise the usability of the dataset.

Future releases will include data from sub-06 and sub-07, who participated under a new experimental paradigm. These will be published as part of a new dataset, Chisco 2.0. We invite you to stay tuned for further updates.

## Dataset Structure

### Root Directory

- `dataset_description.json`
- `participants.tsv`
- `README`
- `derivatives/`
- `sub-01/` to `sub-05/`
- `textdataset/`
- `json/`

### Raw Data

The root directory contains folders `sub-01` to `sub-05` with raw data. Each participant's folder contains 5-6 session folders, corresponding to data collected over 5-6 days.

### Preprocessed Data

Preprocessed data is stored in the `derivatives` folder in both fif and pkl formats.

### Text Data

The `textdataset` folder and `json` folder contain text data used to stimulate the participants.

# Chisco数据集

本数据集为中文想象语音数据集，共包含5名受试者，编号依次为sub-01至sub-05。数据集涵盖fif与pkl两种格式的原始数据与预处理后数据。更多相关信息可访问：https://github.com/zhangzihan-is-good/Chisco

## 补充说明
数据集初始版本仅包含3名受试者（sub-01至sub-03）的数据，相关细节已在Chisco系列研究成果中详述。后续新增了另外2名受试者（sub-04与sub-05）的数据。在初始版本发布至新增数据入库的间隔期间，BIDS（Brain Imaging Data Structure）协议进行了版本更新。为保留研究论文中所载数据处理代码的完整性与一致性，本次补充的数据仍遵循旧版BIDS协议。因此，网站上的BIDS验证工具可能会报错，但此类问题不会影响数据集的实际可用性。

后续版本将新增采用全新实验范式采集的sub-06与sub-07受试者数据，该部分数据将作为全新数据集Chisco 2.0的内容发布。敬请关注后续更新。

## 数据集结构
### 根目录
- `dataset_description.json`
- `participants.tsv`
- `README`
- `derivatives/`
- `sub-01/` 至 `sub-05/`
- `textdataset/`
- `json/`

### 原始数据
根目录下包含sub-01至sub-05共5个受试者文件夹，存储原始数据。每名受试者的文件夹内包含5~6个会话文件夹，分别对应5~6天的采集数据。

### 预处理数据
预处理后的数据存储于`derivatives`文件夹中，同样提供fif与pkl两种格式。

### 文本数据
`textdataset`与`json`文件夹内包含用于诱发受试者产生想象语音的文本刺激材料。
