Statgraphics

Statgraphics is a comprehensive statistical software suite designed for both basic and advanced data analysis. Originating in 1980 at Princeton University under Dr. Neil W. Polhemus, it was one of the pioneering tools for statistical computing on personal computers, with its public release in 1982 marking an early milestone in data science software. Over the years, it has evolved into a robust platform for data science, offering tools for regression analysis, ANOVA, multivariate statistics,...

Area of Science:

  • Genetics
  • Bioinformatics
  • Population Genetics

Background:

  • Microsatellite data analysis in polyploids is challenging due to software limitations.
  • Autopolyploid and allopolyploid genetic structures require specialized analytical approaches.

Purpose of the Study:

  • To introduce POLYSAT, an R package designed for manipulating and analyzing microsatellite data in autopolyploid and allopolyploid organisms.
  • To provide a versatile tool capable of handling diverse ploidy levels and mixed-ploidy populations.

Main Methods:

  • POLYSAT imports and exports data in eight formats.
  • It calculates pairwise distances using stepwise mutation and infinite alleles models.
  • The package estimates ploidy, allele frequencies, and pairwise F(ST) values.

Main Results:

  • POLYSAT accommodates genotype data of any ploidy, including mixed-ploidy populations.
  • It accounts for ambiguous allele copy numbers in partial heterozygotes.
  • The software offers comprehensive data handling and population genetic analysis capabilities.

Conclusions:

  • POLYSAT effectively remedies the lack of specialized software for polyploid microsatellite data analysis.
  • The package is freely available on CRAN with a tutorial, promoting wider adoption in genetic research.
