# Slide scan

Slide scan creates a digital copy of the slide and provides it on the Celly website.

The test works just in configuration with [motorized stage](/config/stage.md) connected. 

### **Initial settings**

Open the Celly App -> settings (gear icon):

* Crop: 0.10-0.15 (green rectangle shouldn't fall on the black borders)  
* Mini-map: Off 
* Motorized Stage: On (can require app restart)
* Motorized Slide Scan: On 
* Skip prescan step: On
* Virtual pad: On
* Adapter: Other 
* Recording: Off

Open the Celly App -> configure analysis -> Type = Slide Scan.

Now we should make important calibrations.  

### Set scan area

Settings -> Set scan area -> Move with virtual pad, to take the scan area.

### Color calibration

Move with Virtual Pad to the empty area.

Settings -> Choose Objective magnification x4 (+ set physically x4 objective) -> calibrate color. 

Repeat the procedure for all magnifications. After the calibrations restart the app. 

### Height calibration

Move with Virtual Pad to area with tissue. Set x10 objective.

Settings -> Calibrate height -> wait for the device automatically find the best focus. 

Now you can make slide scans. 

### Scanning

Open the Celly App -> configure analysis -> Type = Slide Scan.

Push "Start" button and follow instructions. 

After the step go to the [**website**](https://app.celly.ai). Open the [**Tests**](https://app.celly.ai/app/analysis/) page. Push the **View** button to open your scan.
