Export Labeled Signal Sets and Signal Label Definitions
At the end of a labeling session, you can export any signal sets that you labeled or any label definitions that you created. You can export labeled signal sets and definitions either to MAT-files or to the MATLAB® Workspace. Signal Labeler exports labeled signals as labeledSignalSet
objects.
Export Label Definitions
To export signal label definitions, click Export on the
Labeler tab and select To Workspace
or To File
under Label
Definitions
. In the dialog box, specify the name of a variable or
MAT-file. The specified file or variable contains an array of signalLabelDefinition
objects with all the definitions you created, imported, and modified in the current
Signal Labeler session.
Note
If you want to reuse signal label definitions created during a Signal Labeler session, you must export the definitions to a MAT-file and import them in a subsequent session.
Export Labeled Signal Sets
To export new labeled signal sets, click Export on the
Labeler tab and select To Workspace
or To File
under Labeled Signal
Sets
. In the dialog box, specify the name of a variable or MAT-file
and an optional brief description. The variable or file contains a labeledSignalSet
object that merges all the signals, label definitions,
and label values that you created, imported, and modified in the current Signal
Labeler session. All signals that contain time information are converted to
MATLAB timetables.
Note
When exporting labeled signal sets, Signal Labeler converts all
signals with time information to timetables. This conversion results in a deeper
hierarchy of nested channels in the exported labeledSignalSet
object. You can see the deeper hierarchy if you import the labeled signal set
again into the app.
