napari-omaas

napari-OMAAS stands for Optical Mapping Acquisition and Analysis Software for panoramic heart imaging.

This napari plugin intends to be an analysis and acquisition tool for optical mapping in potentiometric (V_m) or calcium (Ca²⁺) fluorescence signals obtained from panoramic imaging of intact hearts.

It supports reading images in .sif format and binary files generated from Andor Technologies cameras powered by the sif_parser python module.

Examples

Plot profile

The following example ilustrate how to perform normalization (pixelwise) on a time serie image and plot its 2d profile along the t dimension withing the averaged ROI selected pixels.

---

APD estimation

The next example shows how to compute action potential duration (APD) in the same image stack.

---

You can also perform additional operations on images, such as normalization, temporal/spatial filters, segmentation, but also apply more advanced image processing methods such as motion tracking/compensation, etc.

Roadmap

This plugin was aimed to have two major components: analysis and acquisition. Bellow is a list of the current features that napari-omaas supports:

Analysis Features

• Read sif files from Andor Technologies.
• Display time profile of ROIs on image sequences.
• Normalize images.
  • Perform peak analysis of action potential / Calcium traces.
  • Add motion correction.
  • APD analysis.
  • Create activation maps.
  • Segment images.
  • Automatic crop and alignment of heart ROIs.
• Export results, metadata and analysis log.

Acquisition Features

• Control Zyla camera for the acquisition of data
  • test using the PYME module
• Real-time analysis(?)
