Fig. 2From: GBS-SNP-CROP: a reference-optional pipeline for SNP discovery and plant germplasm characterization using variable length, paired-end genotyping-by-sequencing dataStructure of the final SNP genotyping matrix. As shown here, the GBS-SNP-CROP final genotyping matrix contains summary statistics as well as complete genotype-specific alignment data for each SNP called. The cells in red represent instances in which a genotypic state could not be assigned, either due to insufficient read depth (-|0/4) or a read depth ratio outside of the user-specified acceptable range (-|132/5)Back to article page
