I have been trying this for a while and have been spending too much time on this.
I saw, and downloaded, Dmitri's stopsigndetector workspace and had a go at it myself. I just have no way of getting it to work at all. Sometimes it seems to get a result (which never makes any sense), but running the same workspace again will then result in a crash.
the problems I encounter:
- Sample preparer just doesn't work at all. Rejects incomming feauture without an error.
- sample generator. Sometimes works, sometimes doesn't. Sometimes gives the error 'invalid background description fie', a file the transformer generates itself..?
- instability: sometimes any of the 4 transformers (sample preparer, sample generator, trainer and detector) just crashes without an error
- Lack of documentation
I tried the relative path trick, without it nothing works, but that didn't help. I downloaded Dimitri'workspace: Doesnt'work. Crashes on the samplepreparer, no error message.
