Resuming iteration
!CONTINUE
!CONTINUE
is used to
restart/resume iterations from the point reached in a previous
run. This qualifier can alternately be set from the
command line
using
the option letters
C
(continue) or
F
(final) options
the
top job control line
using
!CONTINUE
or
!FINAL.
After each iteration, ASReml
writes the current values of the variance parameters to a file with extension
.rsv
(re-start values) with
information to identify individual variance parameters.
The
!CONTINUE
qualifier causes ASReml to scan the
.rsv
file for parameter values related to the current model replacing the
values obtained from the
.as
file before iteration
resumes. If
the model has changed, ASReml will pick up the values it recognises as
being for the same terms. Furthermore, ASReml will use estimates in
the
.rsv
file for certain models to
provide starting values for
certain more general models,
inserting reasonable defaults where
necessary. The transitions recognised are
