Specification
Alias: None
Arguments: None
Default: annotated format
Description
An annotated tabular file is a whitespace-separated text file with one leading header row of comments/column labels. For experiment data files, each subsequent row contains an experiment ID, followed by data for configuration variables, observations, and/or observation errors, depending on context.
Default Behavior
By default, Dakota imports tabular experiment data files in annotated
format. The annotated
keyword can be used to explicitly specify
this.
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 annotated experimental data file containing a header row, leading exp_id column, and experiment data in a calibration study
