Description
A custom-annotated tabular file is a whitespace-separated text file
containing experiment data, including configuration variables,
observatiions, and/or observation errors, depending on context. For
experiment import, custom-annotated allows user options for whether
header
row and exp_id
column appear in the tabular file, thus
bridging freeform
and (fully) annotated
.
Default Behavior
By default, Dakota imports tabular experiment data files in annotated
format. The custom_annotated
keyword, followed by options can be
used to select other formats.
Usage Tips
Prior to October 2011, calibration and surrogate data files were in free-form format. They now default to
annotated
format, thoughfreeform
remains an option.When importing tabular data, a warning will be generated if a specific number of data are expected, but extra is found and an error generated when there is insufficient data.
Examples
Import an experimental data file containing a header row, no leading exp_id column, and experiment data in a calibration study
