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
annotated format, though freeform remains an option.Import an experimental data file containing a header row, no leading exp_id column, and experiment data in a calibration study
