classifier and feature aggregator

[ryana]

Dear all,

I am using OpenViBE for Brain Products. I encountered few problems concerning the aggregator and classifier when using handball-replay.xml given in the package.

[ INF ] Importing scenario in XML Format...
[WARNING] Box algorithm descriptor not found (0x5fe23d17, 0x95b0452c)
[WARNING] Box algorithm descriptor not found (0x00682417, 0x453635f9)

May I know why the classifier and feature aggregator is not found? I have directed the classifier in the replay scenario to the trained classifier (.cfg) , and the online recordings (generated from step 4 of MI session) to the generic stream reader. Did I miss anything?

Million thanks,
Ryana

Hi,

Could you tell us which version of OpenViBE you use and on what OS?
Also, are you sure that the classification plugin and the feature extraction plugin are compiled? Do you see other classification boxes (Voting Classifier and Classifier Trainer) in the designer ?
If not, the plugins is not compiled / not loaded by the designer.

Check the root CMakeList.txt to see if these plugins compilation is not disabled and try clean and rebuild.
