MapManager QTX 20

MapManager QTX 20 is a classic genetics application for building linkage maps and mapping quantitative trait loci (QTL) from experimental cross data. Designed for laboratory genetics workflows, it helps researchers organize genotype/phenotype datasets, construct linkage groups, and scan the genome for QTL using well-established statistical methods. It is widely used for mouse, rat, and other model-organism crosses.

Key capabilities:

• Linkage mapping: Group and order markers, estimate recombination fractions, and compute map distances (e.g., Haldane, Kosambi).
• QTL analysis: Perform marker regression and interval mapping to generate LOD/LRS profiles and estimate additive/dominance effects.
• Significance assessment: Use permutation testing to derive experiment-wide thresholds for QTL detection.
• Data management: Import/export plain-text data, edit datasets, handle missing data, and run basic quality checks for genotyping errors or duplicate markers.
• Visualization and reporting: Produce linkage group diagrams, genome scan plots, and printable summaries suitable for documentation and publication workflows.
• Cross support: Works with common experimental designs such as backcross and intercross (F2), and accommodates codominant and dominant markers.

Typical users include quantitative geneticists and molecular biologists who need a robust, standalone tool to convert raw genotypes and phenotypes into interpretable linkage maps and QTL results.
