Hi, Yes I came to the same conclusion, you need to change the main.cpp if you want to add settings for example, which is completely odd, I did not see anywhere why this problem could occur with a c++ software. But thanks for taking your time for answering, it seems that there are a lot of untold mys...

Hi, Thank you for your answer, sending int with the stimulation is possible, the identifier will just send the number, I think the limit is uint32, after this my memory was overloaded when I tried to send a stimulation this big. However, you cannot send directly negative int (it will give you a giga...

Hi, I am trying to create a box with an integer as an output, I want to send a score to a Matlab box. However since the only output compatible is a stimulation I don't know how the conversion is done. I am sending the git link of the .h and the .cpp https://github.com/TristanVenot/Score.git Thank yo...

Hi !

Thank you so much !!
I am sorry it was so obvious...
However I tried and it still gives the same result...
A thing strange to make it work is to start in the main.cpp to put first VisualInterfaceDesc and then HandDesc.
But I don't know why...

Hi again, I seem to have a problem with the Designer of openvibe, I developed different boxes of visualization but systematically when I launch the designer one of the warnings is : [WARNING] Duplicate plugin object descriptor class identifier [Hand] and [VisualInterface]... second one is ignored Bu...

Hi, I am now trying to see how to use the Matrix which arrives from the Classifier into GrazVisualization, I know what Graz Visualization does with the data received but I don't know the nature of the data at the beginning : is it a matrix ? a vector ? In the process function of Graz, the setMatrixB...

Hi,
thank you very much everything works now !

Hi ! No, I did not change all the files, just one but was unnecessary to upload it, sorry ! I think I missed the point of the stimulation update, however, I find it odd because the program does receive the stimulation however the m_currentDirection (the variable) which gives right or left does not s...

Hi, I am now trying to get different visualization for different directions of stimulation (just as in GrazVisualization), I have a problem with the transfer of the information from the SetSimulation function to the redraw function. Does the process function permit to make a link between the eDirect...

Here is the new depository : https://github.com/TristanVenot/openvibe2.0.git There was also a change in the share folder of dist/extras-release to include the gtk extension for my file. This is the path of my .cpp just in case : openvibe-2.2.0-src\extras\contrib\plugins\processing\signal-processing\...

Hi, It works, it was a matter of priority of constructor, the program had a default constructor, by creating a new constructor, it didn't know which one to deal with therefore it was signaling an error. I created a parallel box which was exactly the same but with a different name, by doing that the ...

Hi thank you,

I am going to see what I can do, but I just followed this tutorial :

Hi,
Python has been found ! Thank you this part of the problem is solved!

Sorry I did put it in private, now it is public :

Thank you again,

Hi, Thank you for your answer, it seems that there is a problem indeed with python, it says : Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is at least version "2.7") -- FAILED to find Python (needs v2.7 with bitness matching build target x86) however Python 2.7...

Hi, I am trying to develop an interface for my internship which is a bit like the GrazVisalization one. I have several questions : -first is there a tutorial focused on how to develop a boxe using the visualization toolkit and gtk.h ? -In one of my attempt I was starting to build what was required w...
