Q, minimum Phred-like SNV quality score (Li et al., 2008).
Min depth, minimum number of reads.
Min ave depth, minimum average number of reads across all genotypes.
Missing (%), maximum percentage of missing genotype data allowed for a given locus.
Minor alleles, minimum number of copies of the minor allele among all genotypes.
Max |FIS|, maximum deviation of observed genotype frequencies from Hardy–Weinberg expectations, FIS = 1 – Ho/He, where Ho and He are the observed and expected heterozygosities.
Min het reads, minimum proportion of reads supporting the less frequent allele in a heterozygous genotype.
No. of alleles, number of SNV alleles detected.
No. of loci (Sorg), number of SNVs that passed all filtering criteria based on alignments to the Sorghum bicolor genome.
Ave MAF (Sorg), average minor allele frequency for SNVs that passed all filtering criteria based on alignments to the Sorghum bicolor genome.
Ave r21 kb (Sorg), average linkage disequilibrium (r2, calculated as genotypic correlation) for pairs of loci with MAF ≥ 0.10 that aligned within 1 kb of one another in the Sorghum bicolor genome.
No. of loci (Misc), number of SNVs that passed all filtering criteria based on alignments to an M. sinensis pseudo-reference.
Ave MAF (Misc), average minor allele frequency for SNVs that passed all filtering criteria based on alignments to an M. sinensis pseudo-reference.
NA, not applicable.
