napari plugin for nd tiff folders with optional OpenCl-based deskewing.

Built-in support for folders of (skewed) lattice light sheet tiffs.

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

• Drag and drop a folder of tiffs onto napari window to view easily
  • (currently designed to detect lattice light sheet tiffs, but easily adjustable)
• If lattice Settings.txt file is found, will deskew automatically (only if necessary)
• Lazily loads dataset on demand. quickly load preview your data.
• Handles .zip archives as well! Just directly compress your tiff folder, then drop it into napari.
• All-openCL deskewing, works on GPU as well as CPU, falls back to scipy if pyopencl is unavailable.

It would not be hard to support arbitrary filenaming patterns! If you have a folder of tiffs with a consistent naming scheme and would like to take advantage of this plugin, feel free to open an issue!

You can install napari-ndtiffs via pip:

pip install napari-ndtiffs

To also install PyOpenCL (for faster deskewing):

pip install napari-ndtiffs[opencl]

In most cases, just drop your folder onto napari, or use viewer.open("path")

You can control things like voxel size and deskewing angle as follows:

from napari_ndtiffs import parameter_override
import napari

viewer = napari.Viewer()
with parameter_override(angle=45, name="my image"):
    viewer.open("path/to/folder", plugin="ndtiffs")

Valid keys for parameter_override include:

• dx: (float) the pixel size, in microns
• dz: (float)the z step size, in microns
• deskew: (bool) whether or not to deskew, (by default, will deskew if angle > 0, or if a lattice metadata file is detected that requires deskewing)
• angle: (float) the angle of the light sheet relative to the coverslip
• padval: (float) the value with which to pad the image edges when deskewing (default is 0)
• contrast_limits: (2-tuple of int) (min, max) contrast_limits to use when viewing the image
• name: (str) an optional name for the image

Try it out with test data: download sample data

You can unzip if you like, or just drag the zip file onto the napari window.

Or, from command line, use:

napari path/to/lls_mitosis.zip

To monitor file io and deskew activity, enter the following in the napari console:

import logging
logging.getLogger('napari_llsfolder').setLevel('DEBUG')
