General scheme of the procedures we followed for each component. a Procedures for golden standard (A.1) and ascertainment bias (A.2); b Procedure for GWAS performance based on simulated matrix; c Procedure for comparison of the effect of imputation in a real phenotypic dataset. Each procedure details the germplasm, genotypic and phenotypic dataset used, as well as simulation approach to obtain each phenotypic vector and GWAS analysis marker score matrices used. Procedures that used wheat data are in green and procedures that used barley data are in purple.
