# Data Structure
Data is saved in HDF5 Format in the following general structure. Note that single arm tasks are missing a few of these folders.
```bash

# Data Recombination
Since HuggingFace has a limit on single file size, you must recombine the data to obtain the full dataset for certain HDF5 files.
After downloading the split files, follow this guide.
**Merging Instructions:**
1. **Navigate to the Download Directory:**
```bash
cd path_to_downloaded_files
```
2. **Merge Files Using `cat`:**
Use the `cat` command to concatenate the split parts. Replace `filename.part_*` with your actual file name.
```bash
cat filename.part_* > filename.tar
```
**Example:**
```bash
cat DexWild_Data.part_* > DexWild_Data.tar
```
3. **Verify the Merged File:**
Ensure that the merged file size matches the original file size before merging. You can use the `ls -lh` command to check file sizes.
```bash
ls -lh DexWild_Data.tar
```
4. **Extract the Dataset:**
Once merged, extract the dataset using the `tar` command:
```bash
tar -xvf DexWild_Data.tar
```
