Datafile line qualifiers


Qualifiers modify the operation of ASReml. There are a large number of qualifiers, most are relevant to particular circumstances.


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.
