VPREDICT

VPREDICT [pinflenme] [ !DEFINE ]

Processing of a .pin file is activated from within the .as file by including a VPREDICT directive. The VPREDICT line may appear anywhere in the .as file but it is recommended it be placed after the model line. It is recognised by the characters VPR in character positions 1:3 of a line. It is processed after the job (part/cycle) has finished. There are four forms of the VPREDICT directive.
  • If the .pin file exists and has the same name as the jobname (including any suffix appended by using !RENAME), just specify the VPREDICT directive.
  • If the .pin file exists but has a different name to the jobname, specify the VPREDICT directive with the .pin file name as its argument.
  • If the .pin file does not exist or must be reformed, a name argument for the file is optional but the !DEFINE qualifier should be set. Then the lines of the .pin file should follow on the next lines, terminated by a blank line.

    In this example, the relevant lines of the .asr file have been pasted into the .as file just to confirm the order of terms. ASReml will usually reorder the random terms from that specified in the model to an order of increasing size as a processing efficiency strategy. It is important to check the VPREDICT commands match the actual order ASReml uses.
