XPOSE: Transpose Case Data into Task Data

Last updated 19 Nov 97

XPOSE creates a Task Data file from an input Case Data file. This file is similar in structure to the Case Data file, with the major difference being that the tasks are switched (transposed) with the cases. The file is task oriented. This allows the unique capability of clustering tasks using OVRLAP.

Program Invocation

The specific syntax for program invocation varies between operating systems. This document diplays the code for the AIX version.

@codap xpose <opt> <ssss> <CDf> <CD6> <TT> [<TFf>]

ssss:    The study number
opt:     Program Options (none currently supported)
CDf:     Input Case Data file (Usually CD100)
CD6:     Output Task Data file (Usually CD600)
TT:      Input Task Title file
TFf:     Input Task Factor file, required if membership or task selection masks
	 are used.

XPOSE Control Card

XPOSE <stdy> <method> [<member>] [<factor> <typ>]

XPOSE:   cc 01-05  The literal 'XPOSE'
stdy:    cc 07-10  The four digit study number
method:  cc 12     default = transpose adjusted percent time spent based on the
		   task selection mask
		   D = transpose do/don't do (1.0 or 0.0)
		   P = transpose percent time spent
		   R = transpose raw task responses
member:  cc 14-19  The membership mask for restricting cases
factor:  cc 21-26  The task factor for restricting tasks
typ:     cc 28-30  The task factor type

Title Card (optional)

If this card is not present, the title for the output Task Data file will be identical to the Case Data file title.

TITLE <title>
TITLE:   cc 01-05  The literal 'TITLE'
title:   cc 07-66  The title for the Task Data file
Example

@codap xpose - ssss cd100 cd600 tt001
XPOSE ssss R
TITLE New output task data file title

Case Data file cd100 will be transposed. The raw task responses will be used for all cases rather than the default of adjusted, transposed percentages.
