2Selects free-form tabular file format for experiment data

4Description::
5
6A freeform tabular file is whitespace-separated text file with no
7leading header row and no leading columns. For experiment data files,
8each row contains data for configuration variables, observatiions,
9and/or observation errors, depending on context.
10
11<b> Default Behavior </b>
12
13By default, Dakota imports tabular experiment data files in annotated
14format.  Specify \c freeform to instead select this format.

16<b> Usage Tips </b>
17
18\li Prior to October 2011, calibration and surrogate data files were
19in free-form format. They now default to \c annotated format, though \c
20freeform remains an option.
21
22\li When importing tabular data, a warning will be generated if a
23specific number of data are expected, but extra is found and an error
24generated when there is insufficient data.
