napari-mat-images 0.1.3

A plugin to load images stored in MATLAB .mat files with napari

napari-mat-images

Features

This plugin loads image variables stored in MATLAB .mat files into napari.

It loads any variable that looks like an image. Presently, that includes any array with more than two dimensions with size greater than 20 pixels (determined by shape_is_image()).

If loading a variable with 3 or more dimensions, the plugin assumes that it is a stack of images, and the dimension with greatest size is the axis of the stack.

Loading Large Files

If loading a large .mat file saved in HDF5/v7.3 format, chunks of the images are loaded as needed, resulting in fast initial load, but potentially slower scrolling.

Slices of the image stacks are randomly sampled to determine min/max contrast values.

Requirements

This plugin relies on scipy to load small .mat files and h5py (with dask) to load larger HDF5/v7.3 .mat files.

It implicitly requires napari for use.

Installation

napari-mat-images requires napari to be installed, although it is not listed as a requirement for installation. This plugin relies on plugin functionality found in napari version > 0.2.12. This can be installed via pip from PyPI:

$ pip install napari>0.2.12

You can install napari-mat-images via pip from PyPI:

$ pip install napari-mat-images

Usage

Once installed, the plugin will be used whenever trying to load a .mat file. This can be done from the napari GUI or commandline:

$ napari my_file.mat
