Features concatenation as a matrix

[nauger]

Hello,
I was wondering if it would be possible to store the feature vectors in a matrix during offline learning and use this matrix to process a batch analysis with the standard box in openvibe. I noticed that we need to wait for reading the signal we recorded during a learning session, which takes time even though we can fast forward it. Moreover generic stream file is quite heavy in memory in comparison to this matrix.

I suppose matlab boxes will be needed in case there is no box for that purpose.

Thank you in advance for your answer,
Nicolas.

Dear Nicolas,

just save the extracted "feature vector" stream to a file using the generic stream writer box, then read it back (fast forwarding it) with the stream reader box in your other scenario

I hope this helps,
Best regards,
Yann
