OryzaSNPs

Description

OryzaSNPs is a dataset of SNP (Single Nucleotide Polymorphism) genotypes and associated phenotypic traits for Oryza species. The dataset is designed for machine learning, statistical genetics, and genotype–phenotype association studies.

Dataset Structure

Split: train/test

Each row corresponds to one individual (specimen).

  • genotype (int8, shape: 177650)
    Encoded SNP genotypes across the genome

  • phenotypes (float32, shape: 19)
    Quantitative or encoded categorical traits

Auxiliary: snps

Metadata describing each SNP (shared across all samples).

  • chrom: Chromosome identifier
  • pos: Normalized genomic position (scaled to [0, 1] within chromosome)
  • allele: Encoded allele information

Genotype Encoding

Each SNP genotype is encoded as an integer in the set:

Value Meaning
-1 Missing genotype (no reliable call)
0 Homozygous reference allele
1 Heterozygous (one reference, one alternate allele)
2 Homozygous alternate allele
