To use MAP on a VAX computer, the user must supply two input files — a raw data file and an input specification file (map.in) containing a series of keywords. Each of the item identified from SNEA associated with at least two common genes. Finally, four additional sets of traits have been analyzed and provided similar conclusions. Gains with selection, considering each environment, ranged from 9.17 to 20.66%, when five hybrids were selected. 2019;24:562–575. Fig. 2008). Multi-trait meta-analysis chi-squared statistic. AU - Turley, Patrick. 5d). 1. We proposed a multi-trait association analysis method based on multivariate mixed linear model including additive, dominance, epistasis effects of QTS and their interaction effects with environments. (Author/PN) While appealing, most existing methods focus on analyzing a relatively small number of traits, and may yield inflated Type 1 error rates when a large number of traits need to be analyzed jointly.

Across the multi-trait methods, mvGWAS had a slightly higher true-positive detection rate than the PC1 GWAS when all of the simulated trait heritabilities were either 0.9 or 0.5. By Keith F. Widaman. Multi-trait association analysis efficiently identifies signals caused by pleiotropic loci. Multi-trait analysis has also been found to substantially increase prediction accuracy when some traits are observed in all individuals but the trait of interest is not observed in the individuals in the test set (Pszczola et al.
