Description

A custom-annotated tabular file is a whitespace-separated text file typically containing row data for variables, or variables followed by responses, though the format is used for other tabular exports/imports as well. Custom-annotated allows user options for whether header row, eval_id column, and interface_id column appear in the tabular file, thus bridging freeform and (fully) annotated.

Default Behavior

The annotated format is the default for tabular export/import. To control which header row and columns are in the input/output, specify custom_annotated, followed by options, in the relevant export/import context.

Usage Tips

  • Prior to October 2011, calibration and surrogate data files were in free-form format. They now default to annotated format, though freeform 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.

  • Some TPLs like SCOLIB and JEGA manage their own file I/O and only support the freeform option.

Examples

Export a custom-annotated tabular file in Dakota 6.0 format, which contained only header and eval_id (no interface_id), and data for variables and responses. Input file fragment:

environment
  tabular_data
    tabular_data_file = 'dakota_summary.dat'
    custom_annotated header eval_id

Resulting tabular file:

eval_id             x1             x2         obj_fn nln_ineq_con_1 nln_ineq_con_2
