napari-locpix

Load in SMLM data and annotate within napari

---

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation¶

You can install napari-locpix via pip:

pip install napari-locpix

To install latest development version :

pip install git+https://github.com/oubino/napari-locpix.git

Usage¶

This plugin allows a user to

1. Read in SMLM data
2. Visualise SMLM data in a histogram
3. Add segmentations to the data
4. Extract the underlying localisations from the segmentations

IO¶

The input data can be in the form of a .csv or .parquet.

We expect there to be 4 columns at least, which should he identified inthe file column selection:

• X coordinate
• Y coordinate
• Frame
• Channel

If the data has been annotated with this software we can also load this in. Note however we currently only support loading in annotated data saved as a .parquet folder. Therefore, we recommend always keeping a .parquet copy until loading in an annotated .csv is supported.

The data can be outputted to a .parquet or a .csv

Drop localisations with zero label, gives you the option to only save the localisations which have been annotated i.e. labels 1 and above.

Channels labels allows you to give a real name label to each of the channels e.g. Chan 0 label: 'Alexa 647'

Visualisation¶

Using the render button you can render the loaded in data according to the histogram settings

X/Y bins defines the number of bins for the histogram

Vis interpolation defines how to interpolate the image before viewing

Annotations¶

Annotations can be added using Napari's viewer.

Simply click the add Labels.

Note that this software will expect the labels to be called "Labels"
