Mitotic yeast image analysis

CytoCV

Structured analysis for DeltaVision microscopy workflows, built through a University of Washington Bothell and University of Utah research collaboration.

Overview

What CytoCV Is

CytoCV is a web-based analysis platform for DeltaVision .dv microscopy of mitotic yeast cells. It is designed to keep image files, channel interpretation, scale context, and measurement outputs connected in one browser-based workflow.

The platform supports a modern default analysis path centered on structural segmentation plus red and green fluorescence measurements, while keeping older DAPI-based workflows available as legacy paths when they are needed.

  • DIC Structure
    Structural channel used for segmentation.
  • mCherry Red
    Red-signal contour and distance context.
  • GFP Green
    Green intensity and dot measurements.
  • DAPI Legacy
    Legacy nucleus-related analysis path.

Research Need

Why Researchers Need It

Microscopy studies often require researchers to inspect many cells, compare fluorescent signals, and record measurements across repeated experiments. Doing that cell by cell by eye can take time, scale poorly as datasets grow, and introduce inconsistency in how cells are selected or measured.

CytoCV is designed to reduce manual analysis time and help researchers quantify more cells more consistently, while preserving the connection between the original image stack and the numbers produced from it.

Workflow

How the Workflow Works

Researchers upload DeltaVision .dv files, and CytoCV validates the channels required for the selected workflow before analysis proceeds. Preview images are generated first so the file can be checked before segmentation and measurement begin.

The platform then uses DIC, a structural brightfield-like channel, as the input for Mask R-CNN-based cell segmentation. After cells are segmented, CytoCV computes per-cell measurements and presents the results for review and export.

Workflow outputs

Measurements

What CytoCV Measures

  • mCherry line intensity Measures GFP intensity along the line drawn between paired red dot centers.
  • GFP dot classification and biorientation Classifies GFP-dot behavior relative to paired red signals in the modern workflow.
  • Green and red contour intensity summaries Calculates contour-based intensity combinations across red and green channels.
  • Nuclear and cellular intensity Uses either a red-defined or green-defined nucleus contour and measures the opposite channel inside the nucleus and across the whole cell.
DAPI-based measurements remain available as legacy workflows, not the main default path.

Biological Value

Why This Matters Biologically

These measurements help researchers compare signal localization between the nucleus and the whole cell, examine how paired red and green signals relate to one another, and evaluate patterns across yeast populations or mutant conditions.

That makes CytoCV useful for studies where the question depends on where a fluorescent signal is located, how paired markers behave together, or how to compare more cells through a more repeatable analysis process than manual review alone.
