Datafile line qualifiers
Qualifiers modify the operation of ASReml. There are a
large number of qualifiers, most are relevant to particular
A qualifier is recognised as a letter sequence preceded by
an explanation mark. Generally, the first three letters are sufficient to
specify a qualifier although using the full name will normally
make the job clearer to understand.
Some qualifiers have no argument. Most have a default argument.
A few have multiple arguments.
These datafile line qualifiers are placed either on the
line that specifies the name of the data file,
or on immediately following lines. A few, particularly those
with multiple arguments like
!CONTRAST, !PVAL, !SPLINE, !SUBSET
must be put on separate lines by themselves.
