Is there a way to filter annotations by length in the Report Generator?

In a simulink model that uses areas for visual aids, each area is numbered. However each of these numbered areas results in a new entry. In reality we would like to skip annotations that are only 1-4 characters in length when using the annotation loop. Is there a way to make a custom component that is capable of doing this?

A little late, hopefully this will help.

You need to use the IF component to filter out unwanted annotations object. Unfortunately, there is no public API to get the current reported annotation handle. To get the current reported annotation handle try the following:

1. Download the attached ZIP file
2. Copy getReportedAnnotation.m to matlabroot/toolbox/rptgenext/rptgenext/@RptgenSL/getReportedAnnotation.m
3. Run the following to update MATLAB toolbox cache

>> rehash toolboxcache

Now in your IF component, use the following expression to keep only annotations that are longer than 4 characters.

numel(get(RptgenSL.getReportedAnnotation, 'Name')) > 4

For a working example, see annotation_ex.rpt within the ZIP file.
