CalMorph

CalMorph analyzes microscopic images of budding yeast to quantify cell shape, nuclear shape and location, and actin distribution for morphological and cell-cycle studies.

Key Features:

• Automated Image Processing: Directly analyzes digital microscopic images of budding yeast to extract morphological data without manual intervention.
• Quantitative Measurements: Generates reproducible quantitative measurements of cellular components, including cell shape, nuclear position, and actin distribution.
• Three-Dimensional Reconstruction from Two-Dimensional Images: Reconstructs three-dimensional bud information from two-dimensional images with a reported error rate below 1%.
• Measurement Validation: Measures diameters of fluorescent beads and other cellular features with high accuracy validated against manufacturer data sheets and manual measurements.

Scientific Applications:

• Cell Cycle Monitoring: Quantifies morphological changes to monitor cell-cycle progression and associate phenotypes with gene products.
• Mutant Analysis: Objectively describes yeast morphological mutants to assess genetic influences on cell structure.

Methodology:

CalMorph employs a robust image processing algorithm to measure diameters of fluorescent beads and other cellular features; this precision is validated by alignment with manufacturer data sheets and consistency with manual measurements, and the software generates reproducible quantitative data.
