Image analysis

MetaXpress or in full name "MetaXpress® High-Content Image Acquisition and Analysis Software" is a commercially available closed source software for high-content analysis from Molecular Devices, LLC.. The program is a kind of visually guided workflow programming environment. There is a programming module called CME (custom module editor) which lets one setup integrated workflows for bioimage analysis with visual feedback. It is designed for high-throughput in connection with a included database which stores the experimental data. 

It has several toolboxes for semiautomated processing of various tasks:

3D Analysis (requires Custom Module Editor), Curve fitting, Transmitted light segmentation (requires Custom Module Editors), Angiogenesis tube formation, Cell cycle, Cell health, Cell scoring , Count nuclei, Granularity, Live/dead , Mitotic index, Micronuclei , Monopole detection, Multi-Wavelength cell scoring, Multi-wavelength translocation, Neurite outgrowth , Transfluor® Assay, Translocation* (includes Translocation-Enhanced*) , Transfluor HT Assay , Nuclear translocation HAT, Cell proliferation HT

After the workflow is setup it is possible to apply it automatically to a stack of stored images. The derived data from those analyses is stored in the metaxpress database and can be exported from there.

The use of each toolbox requires a separate license.

Big-FISH is a python package for the analysis of smFISH images (2D/3D). It includes various methods to analyze microscopy images, such spot detection and segmentation of cells and nuclei.

Fiji plugin to segment oocyte and zona pellucida contours from transmitted light images and extract hundreds of morphological features to describe numerically the oocyte. Segmentation is based on trained neural networks (U-Net) that were trained on both mouse and human oocytes (in prophase and meiosis I) acquired in different conditions. They are freely avaialable on the github repository and can be retrained if necessary. Oocytor also have options to extract hundreds of morphological/intensity features to characterize manually the oocyte (eg perimeter, texture...). These features can also be used in machine learning pipeline for automatic phenotyping.

The BioVoxxel Toolbox is a suite which contains plugins and some macros dealing with image filtering, image segmentation and binary image processing and analysis. The following plugins are hosted here:

• Extended Particle Analyzer
• Binary Feature Extractor
• Speckle Inspector
• Watershed Irregular Features
• EDM Binary Operations
• Filter Check
• Pseudo flat-field correction
• Convoluted Background Subtraction
• 2D Particle Distribution (Distribution_Analysis)
• Cluster Indicator
• SSIDC Cluster Indicator
• Gaussian weighted Median filter
• Adaptive Filter
• Enhance True Color Contrast
• Mode and Differential Limited Mean Binarization
• Basic Recursive Filter

MATLAB app to characterize nanoparticles imaged with super-resolution microscopy. nanoFeatures will read text and csv files from the NIKON and ONI microscopes and from the ThunderSTORM Fiji plugin, then cluster the localizations and filter by size and sphericity and finally output nanoparticle features like size, aspect ratio, and number of localizations per cluster (total and for each channel).
