Hi Hedwig
try this:
RichFeature richFeature = RichFeature.Tools.makeEmptyFeature();
RichLocation richLocation = new SimpleRichLocation(
new SimplePosition(start), new SimplePosition(end), rank, RichLocation.Strand.POSITIVE_STRAND);
richFeature.setLocation(richLocation);
richFeature.setType("misc_feat"); // or get it from RichObjectFactory.
richSequence.getFeatureSet().add(richFeature);
Regards,
khalil

> There is a coding problem in ThinRichSequence (from which SimpleRichSequence and others extend) that allow only Set<Feature> as input, but require the Feature objects to actually be RichFeature objects. This was for a number of reasons that probably seemed good at the time but I have now forgotten what they were. The workaround is to declare your set as a Set<Feature> but populate it with RichFeature objects (as RichFeature extends Feature and so the Set will still accept them).
