Brief description: This course encompasses the background needed to perform genomic
analyses used in Animal Breeding and Genetics with the BLUPF90 programs (Misztal et al.,
2014).

Day 1:

  • Introduction of BLUPF90 family of programs for the analyses of mixed models including single and multiple traits, maternal effects, and repeatability models
    • Renumbering datasets: renumf90
    • Estimation of breeding values and VCE: blupf90+
    • Estimation of breeding values and VCE - Bayesian: gibbsf90+
    • Exercises: use of BLUPF90 programs with real data for single and multiple trait models

Day 2:
  • Introduction to Genomic data
    • History of the use of genomic data
    • Genomic markers
    • Statistics of genomic data
    • Genomic files
  • Quality control for SNP data, genomic and pedigree relationships
    • Call rate
    • Parental exclusions
    • Distributions of diagonals and off-diagonals of G
    • Differences between matched G and A22
    • Eigenvalues/eigenvectors – population stratification
    • preGSf90 and qcf90 for quality control
  • Bash scripting to deal with genotypes, pedigree, and phenotypes
  • Exercise: Data editing with bash scripting and quality control of genomic data

Day 3:
  • Introduction to Genomic Selection
  • Theory of Single-step GBLUP (ssGBLUP)
  • Creating and handling genomic relationship matrices with preGSf90
  • Validation techniques for testing genomic models
    • Prediction accuracy vs. theoretical accuracy
    • Prediction accuracy with and without validationf90
  • Exercises: Use of ssGBLUP with BLUPF90 programs in simulated datasets andvalidation of genomic predictions

Day 4:
  • Estimating SNP effects from GBLUP and ssGBLUP models
  • Indirect predictions using SNP effects
  • Weighted GBLUP and ssGBLUP
  • Single-step Genome-wide association studies (GWAS)
  • Exercises: Compute SNP effects from ssGBLUP, run indirect predictions for young animals, and do ssGWAS (variance explained by SNP and p-values) with BLUPF90 programs

Optional Mandatory pre-course:
Basics of mixed model equation, genomic prediction, and genome-wide association studies (GWAS)

Date: August 31 - September 1, 2026
Time: From 9:00 AM to 4:00 PM
Place: Georg-August University Göttingen, Department of Animal Sciences
Instructor: Prof. Dr. Christine Große-Brinkhaus

Purpose:
This optional pre-course aims to prepare participants for the summer school “Fundamentals and computational methods for genomic prediction and genome-wide association studies (GWAS)” by refreshing the basic concepts of mixed model equation, genomic prediction, and GWAS, and by providing background information. Further, a brief check on technical requirements to work with the BLUPF90 programs will be offered.
