Whats New in Release 4.3
Introduction
These notes relating to ASReml 4.3 are intended
to users familar with ASReml 4.2.
Functional syntax was introduced in ASReml 4.1.
While the original ASReml 3 "Structural"
syntax remains functional, it is no longer included in the primary documentation.
Summary
The following significant changes have been made in ASReml 4.3
Genetic Model effects trimming
has been implemented for MET analyses which results in reductions of computing time (Section 4.4)
ASReml has incorporated some enhancements into factor analytic models that run faster (Section 3.3)).
An eigen-based model transformation
has been implemented that is relevant with a GRM, where this matrix is transformed to a diagonal structure that is more efficient (Section 4.3).
New functionalities to construct genomic matrices have been added, including forming an H (hybrid) matrix and its inverse (Section 4.5), and constructing dominance and epistatic matrices from marker data (Section 4.2).
Job control qualifiers
have been added, particularly associated with generating and saving matrices,
such as the full coefficient matrix and its inverse (Section 1,2),
and
binary forms
of the GIV/GRM (Section 4.1)
New quaifiers
have been added to TABULATE and PREDICT.
Program enhancements
result in most larger jobs running faster. It is possible to
explore which program steps are taking the most time.
