## Importing Data

You can import data from **CSV files**:

- Go to **File → Import CSV file...**
- Supported structure:

| ROI_1 | ROI_2 | ... | ROI_n |
|------|------|-----|------|
| x₀ | x₀ | ... | x₀ |
| x₁ | x₁ | ... | x₁ |
| ... | ... | ... | ... |

- Specify the sampling rate (Hz) when prompted.
- If the dataset is **global** (same trace across ROIs), check the **Global Dataset** option.

**Note:** Only CSVs with **comma (`,`) separator** are supported.  
Need to convert from another separator? Use:  
**Tools → Convert CSV files**

## Plotting and Data Analysis

- After importing, your datasets appear on the left sidebar.
- **Left-click** to activate a dataset.
- **Right-click** for more options (rename, modify, etc.)

---

## Peak Detection

- Activate a dataset, then click **Detect Peaks**.
- Customize detection parameters and watch live detection updates.
- Export detected peak information to CSV.

---

## Video Viewer & Video Converter

- Open the **Video Viewer** under **Tools → Open Video Viewer**.
- Connect video frames to ROI data for synchronized viewing.
- **Video Converter** (Tools → Open Video Converter) lets you:
  - Convert between formats using **FFmpeg** (you must have it installed).

Download FFmpeg from [https://ffmpeg.org/](https://ffmpeg.org/).
