recOrder-napari 0.1.2

Computational microscopy toolkit for label-free imaging

recOrder

This package offers a comprehensive pipeline, command line interface, and napari plugin for quantitative label-free microscopy.

In this repo you will find python tools and UI that allow the user to calibrate microscope hardware, acquire multi-modal data, reconstruct density and anisotropy, and visualize the data.

The acquisition, calibration, background correction, reconstruction, and applications of QLIPP are described in the following E-Life Paper:

Syuan-Ming Guo, Li-Hao Yeh, Jenny Folkesson, Ivan E Ivanov, Anitha P Krishnan, Matthew G Keefe, Ezzat Hashemi, David Shin, Bryant B Chhun, Nathan H Cho, Manuel D Leonetti, May H Han, Tomasz J Nowakowski, Shalin B Mehta, "Revealing architectural order with quantitative label-free imaging and deep learning," eLife 2020;9:e55502 DOI: 10.7554/eLife.55502 (2020).

recOrder is to be used alongside the QLIPP module, whose design has been optimized to fit on a conventional widefield microscope (Panel A below). The QLIPP module allows for the collection of label-free information consisting of the intrinsic anisotropy of the sample and its relative phase (density). All of these measurements are collected through compensated, polarization diverse illumination and quantitatively recovered through recOrder's computational reconstruction pipeline. The overall structure of recOrder can be visualized below in Panel B, highlighting the two different usage modes and their features: graphical user interface (GUI) through napari and command line interfact (CLI).

Dataset

Slides and a dataset shared during a workshop on QLIPP and recOrder can be found on Zenodo.

Installation

Easy installation:

(Optional but recommended) install anaconda and create a virtual environment

conda create -n recorder python
conda activate recorder

Install napari:

pip install "napari[all]"

Open napari and use the Plugin > Install/Uninstall Plugins... menu to install recOrder-napari.

Developer installation:

Install git and conda (either anaconda or miniconda).

Create a conda environment dedicated to recOrder:

conda create -n recorder python
conda activate recorder

Clone this repository:

git clone https://github.com/mehta-lab/recOrder.git

Install recOrder and its dependencies:

cd recOrder
pip install -e ".[dev]"

Optional napari plugin: recOrder includes a napari plugin that can be used to acquire data via MicroManager. To install napari use

pip install "napari[all]"

To run the recOrder plugin use

napari -w recOrder-napari

To acquire data via MicroManager, follow the instructions on the wiki.

Optional GPU: recOrder supports NVIDIA GPU computation with the cupy package. Follow these instructions to install cupy and check its installation with import cupy. To enable gpu processing, set use_gpu: True in the config files.

Command-line usage

Type recOrder.help for instructions on the two command-line modes: recOrder.reconstruct and recOrder.convert.

recOrder.reconstruct

recOrder.reconstruct uses configuration files to select reconstruction parameters. Start with an example configuration file /examples/example_configs/config_example_qlipp.yml and modify the parameters to match your dataset.

Run the reconstruction with

recOrder.reconstruct --config <path/to/config.yml>

The following command-line arguments override parameters specified in the configuration file:

--method (str) method of reconstruction: QLIPP,IPS,UPTI'
--mode (str) mode of reconstruction: 2D, 3D'
--data_dir (str) path to raw data folder'
--save_dir (str) path to folder where reconstructed data will be saved'
--name (str) name under which to save the reconstructed data'
--config (str) path to configuration file (see /examples/example_configs')
--overwrite (bool) True/False whether or not to overwrite data that exists under save_dir/name'

For example, this command uses the QLIPP reconstruction method even if the configuration file specifies a different reconstruction method

recOrder.reconstruct --config /path/to/config.yml --method QLIPP

recOrder.convert

recOrder.convert converts MicroManager tif files to ome-zarr files. For example

recOrder.convert --input <path/to/mm/tifs> --output <path/to/output.zarr>  --data_type ometiff
