Installation

To install the ALE Meta-Analysis Package, run:

pip install jale

Usage

Here’s how to use the project:

JALE requires a project folder that contains 3 files:

1. Experiment Data (Author, Subjects, Coordinates, Tags)
2. Analysis Data (Type of ALE, Tags to be included)
3. Yaml config file (specifying project folder path, filenames and ALE parameters)

The format of these files is very important and you should check the wiki for instructions.

For example files click here.

Running an ALE can be done in two ways:

1. via CLI:

python -m jale /path/to/yaml/file

2. in Python:

from jale.ale import run_ale

run_ale(yaml_path='/path/to/yaml/file')

Features

• Standard ("Main Effect") ALE
• Probabilistic ("Cross-Validated") ALE
• Standard ALE Contrast
• Balanced ALE Contrast
