    Area of Science:

    • Genetics
    • Bioinformatics
    • Computational Biology

    Background:

    • Accurate chromosome analysis is crucial for diagnosing genetic disorders.
    • Manual selection of metaphase spreads for karyotyping is a time-consuming bottleneck in cytogenetics.
    • Existing algorithms have not sufficiently addressed the challenge of selecting suitable metaphase spreads.

    Purpose of the Study:

    • To develop an efficient software tool for identifying suitable metaphase spreads for karyotyping.
    • To automate and streamline the process of chromosome analysis.
    • To overcome the limitations of manual selection in cytogenetic analysis.

    Main Methods:

    • Development of a software tool, MetaSel, employing a rule-based system.
    • Classification of chromosome shapes into four classes: straight, skewed, overlapping, and non-chromosome objects.
    • Utilizing image parameters and a statistical model with a Gaussian distribution to determine classification thresholds.
    • Achieving >90% accuracy in classifying individual chromosomes.

    Main Results:

    • MetaSel successfully classifies chromosome shapes and identifies suitable metaphase spreads.
    • The rule-based system, informed by a Gaussian model, accurately distinguishes between good and poor quality spreads.
    • Individual chromosome classification accuracy exceeds 90%.

    Conclusions:

    • MetaSel provides an efficient method to rank chromosome spread images, aiding cytogeneticists in karyotyping.
    • The software includes comprehensive tools for chromosome editing and karyotyping.
    • MetaSel is freely available for download, facilitating its adoption in research and clinical settings.
