Remarks

The columns attribute specifies the data values to be recorded to file and the column in which they are written. There are two types of columns that can be listed: 1) a reserved keyword representing a particular eye tracker data value, and 2) any property of any element defined in the script. The data values may be specified in any order. On each eye tracker mesage, Inquisit will write a single line of data consisting of each data value specified by the column. Columns will appear in the data file in the specified order.

Examples

The following records 10 columns to the data file:

<data>
/ columns=(date, time, groupId, subjectId, timestamp, leftPixelX, leftPixelY, rightPixelX, rightPixelY, leftValidity, rightValidity, values.totalEarnings, values.dPrime, script.elapsedTime)
</data>
