limax: python utilities for LiMAx

limax is a collection of python utilities for working with LiMAx data with source code available from https://github.com/matthiaskoenig/limax.

The project is developed in collaboration by the Humboldt-University Berlin (Matthias König) and the Jena University Hospital (Hans-Michael Tautenhahn).

Features include:

• Anonymisation of LiMAx raw data files

• Visualization of LiMAx DOB curves

• Calculation of AUC, LiMAx values and other pharmacokinetics parameters from LiMAx DOB curves.

If you have any questions or issues please open an issue.

Installation

limax is available from pypi and can be installed via:

pip install limax

Best practise is to setup a virtual environment example via conda and install the package. First install anaconda via https://docs.anaconda.com/anaconda/install/index.html. To run the limax tool open a terminal app (e.g. Application -> Utilities -> terminal on MacOS) and create the conda environment

conda create -n limax python=3.10
conda activate limax
(limax) pip install limax --upgrade

Usage

Command line tool

After installation LiMAx analysis can be performed using the limax command line tool

$ limax

Common problems

On MacOs the terminal app requires permissions to access files, i.e.

PermissionError: [Errno 1] Operation not permitted

This can be solved by changing the permissions of the terminal app via https://stackoverflow.com/questions/58479686/permissionerror-errno-1-operation-not-permitted-after-macos-catalina-update:

• Go to System Preference->Security and Privacy.

• On the left side click on Full Disk Access

• Now click on bottom left lock icon and enter password to make changes, see Label 3

• Now click on + sign button

• Browse the terminal app from Application -> Utilities
