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 genomephenotypes (
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 |
