 We have prepared two types of data. The first type consists of results on four datasets, obtained using ten SOTA algorithms. This data is in CSV format, which allows users to quickly reproduce the results of the Space article. **This data is already integrated into this repository, so users do not need to download it separately.** The second type is the processed SRT data, which includes gene expression matrices, spatial location information, and H&E images. Due to the large size of this data, it cannot be uploaded to GitHub. Therefore, users will need to download it.

 To facilitate user access, we have uploaded the processed SRT datasets to **[Google Drive](https://drive.google.com/drive/folders/1rXn5_HYpFo514hQXepZnaNJAD5xq9o4Z?usp=drive_link)** and **[BaiduYun](https://pan.baidu.com/s/1qxoq0ttp0BzsvLzBtDUgIg?pwd=3vvv)**.

 To reproduce the results of the Space article, users can run the scripts in the **Demo** folder. The scripts are organized into two folders: **Reference_Methods** and **Reproduce_Scripts**. The **Reference_Methods** folder contains scripts for reproducing the results of the ten SOTA algorithms. The **Reproduce_Scripts** folder contains scripts for reproducing the results of the Space.
 
-Here, for quick illustration, we directly apply Space to the results obtained from 10 SOTA methods. These methods have already been executed. The scripts are asved in **Reference_Methods** folder. The results of these methods are saved in the **Data** folder.
