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.
