Hi,

I'm trying to get the online accuracy in the bci motor imagery scenarios. in scenario 4 I added the Classifier Accuracy Measure box and connected it to both the stimulation outputs of Graz stimulator and classifier processor.

But the display window doesn't show anything and I get the following warnings.

[ WARNING ] Box <Classifier processor> sends inconsistent chunk dates on output [0] (current chunk dates are [266287972,4561255268] whereas previous chunk dates were [0,4294967296])
[ WARNING ] 'Stimulations' streams should have continuously dated chunks
[ WARNING ] Please report to box author and attach your scenario


here is my scenario :

Hi, that box is unfortunately broken in the release version of OpenViBE. I recently fixed it, but we haven't made a new release. If its very important to you, you can try to compile the latest git master version where it should be ok.


Best,
Jussi

Hi,
I would like to ask when the new version of openvibe will be released. I am also waiting for this box to do online classification experiments.
Thank you in advance.

Hi, we don't have a firm deadline for the next release, so I'm adding a hotfix here. It hasn't been thoroughly tested. Just extract it on top of 2.1.0 installation. It has three .dll files that address different issues. These included files should replace the ones in the installation.

- Matlab scripting box crash issues
- Indexing problems in outlier detection box
- Classifier Accuracy measure fix.

Users concerned only with the last should replace just the file 'bin/openvibe-plugins-evaluation.dll' and the files under share/.


Best,
Jussi
