This is a selection of functions providing loading functionalities for files created with ARYELLE series spectrometers from LTB Lasertechnik Berlin GmbH and the Sophi software.

Documentatation of functions and the file format can be found on the corresponding gitlab-page. It is written for Python but function interfaces are the same for Matlab.

Issues can be reported online in the projects issue-tracker.

Installation

Python

Users of Python can install directly from pypi using:

pip install ltbfiles

Then you can use it like this:

import ltbfiles
spec = ltbfiles.load_folder("path/to/folder", extensions=".aryx", interpolate=True)

Matlab

The minimum version required is R2019b. Tests are being run with MATLAB version R2022b and R2024b. Some features are only supported from version R2024b onwards.

The preferred way is to download the latest package from the package registry and install it by double clicking on it. All functions can now be accessed using the prefix ltbfiles.function like:

[Y,x] = ltbfiles.load_folder("path/to/folder", extensions=".aryx", interpolate=true)

You may hit F1 in order get help on any function.

Option2: Bundle a package yourself

Download or clone this project to your local machine and open the folder with MATLAB. Within MATLAB, open the file "ltbfiles_MATLAB-Toolbox.prj". MATLAB should open the "Package a Toolbox" dialog. Click on "Package" within the toolbar. A file named ltbfiles.mltbx is created inside the same folder. By double clicking on it, the toolbox is installed as a package within MATLAB and can now be found by all projects on the given machine. the toolbox-file can also be transferred to and installed on other devices. There is no need to keep the original project on the machine after installing the toolbox.

Option3: Add folder to search path

Download or clone this project to your local machine. Keep the downloaded folder somewhere on the machine and use

addpath(path/to/ltbfiles_MATLAB);

in the beginning of your projects.
