# Installation

## System Requirements

#### Operating System <a href="#id-2spatialimagealignersoftwarearchitectureanddesign-memory" id="id-2spatialimagealignersoftwarearchitectureanddesign-memory"></a>

* Windows 11+
* MacOS 14+ (Apple Silicon)

#### Memory <a href="#id-2spatialimagealignersoftwarearchitectureanddesign-memory" id="id-2spatialimagealignersoftwarearchitectureanddesign-memory"></a>

* Minimum memory: 16 GB
* Recommended memory: 32 GB or higher, for larger, more complex images
* Memory requirements scale with image size and resolution. For example, a 10 x 10 mm image with 0.4 pixels/μm and 3 color channels occupies approximately 1.7 GB of memory.

#### CPU <a href="#id-2spatialimagealignersoftwarearchitectureanddesign-cpu" id="id-2spatialimagealignersoftwarearchitectureanddesign-cpu"></a>

* Designed to perform efficiently on most multi-core CPUs.
* Utilizes optimized libraries like OpenCV for image processing.
* Lower-end processors may result in slower processing times, but tasks should still complete successfully.

#### GPU <a href="#id-2spatialimagealignersoftwarearchitectureanddesign-gpu" id="id-2spatialimagealignersoftwarearchitectureanddesign-gpu"></a>

* Not mandatory, but beneficial for advanced image rendering and visualization via [deck.gl](http://deck.gl/).
* Enhances smoothness of image visualizations.

#### Disk <a href="#id-2spatialimagealignersoftwarearchitectureanddesign-gpu" id="id-2spatialimagealignersoftwarearchitectureanddesign-gpu"></a>

* Illumina Spatial Image Tool requires 4.5 times the disk space of the input image file for processing. For example, a 1 GB image requires 4.5 GB of disk space.

#### **Network**

* Network connection is *required* for exporting sample files directly to the cloud. This is the recommended method, offering greater convenience and streamlined workflows.
* Alternatively, if a connection is *unavailable* or if cloud export is not desired, ISIT provides an option to locally export sample files.

{% hint style="info" %}
**Note:** To export sample files from ISIT directly to the cloud, ensure the application is installed on a PC with a stable network connection.

If a stable network connection is unavailable, use ISIT's local export option.

For further assistance, contact Illumina Support.

## Steps to Install

### First Time Installation

Select, download, and run the appropriate installer for your operating system:

**Windows:**

1. Launch the \*.msi file to begin installation of Illumina Spatial Image Tool.
2. The application will be installed to the default location: "C:\Program Files (x86)\Illumina Spatial Image Tool\\"

**MacOS:**

1. Launch the \*.dmg file and move the app icon into the Applications folder.
2. The application will be installed to the default location: "/Applications/Illumina Spatial Image Tool"

### Updating to a New Application Version

1. Uninstall the currently installed application before installing the new version. (Refer to [Uninstallation](/dragen-stratamap/illumina-spatial-image-tool/uninstallation.md) for steps to uninstall the application.)
2. Install the new version of the application by following the First Time Installation steps above.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.connected.illumina.com/dragen-stratamap/illumina-spatial-image-tool/page.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
