# Getting Fabber¶

## From FSL¶

Fabber is distributed as part of FSL, and this is the easiest way to get Fabber if you want to use existing models for fMRI data . This documentation describes the version of Fabber included with FSL v6.0.1 and above.

Addition tools that can use Fabber will work with a correctly installed FSL distribution although currently not all models we have developed are available in FSL.

## Standalone Fabber distribution¶

Standalone versions of Fabber including a selection of model libraries are available for a number of platforms. These may be useful if you don’t want the rest of FSL or if you need a more up to date version of Fabber than the one included with FSL.

The current standalone release can be found at https://github.com/physimals/fabber_core/releases.

The standalone release can be used with tools requiring a Fabber installation such as the Python API, or Fabber-based plugins for Quantiphyse. You should set the environment variable FABBERDIR to the unpacked distribution directory to ensure these tools can find Fabber. Note that some Quantiphyse plugins require a full FSL installation, notably the ASL plugin.

## Building from source code¶

You can build Fabber from the source code available in the Github repository. You will need an FSL installation for this. For instructions see Building Fabber.
