Re: Features concatenation as a matrix

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

Re: Building OpenViBE with gcc 4.7.2

Hello everyone, just wanted to stress, as a side note, that using native packages for boost broke the builds in the past as boost API sometimes changes. Fedora releases are usually one step ahead from othe linux distros and turning back to native packages may hurt the release process in the future. ...

Re: Driver for deymed's truscan

Dear Rani, I had the opportunity to talk with some people at Deymed in the past. There exists a TCP/IP protocol to communicate with their own software so yes, it is possible to write a driver for those devices. If you feel like you can do it, be sure to get in touch with them and gain access to thei...

Dear Lorena, the level measure box displays rows/columns according to the input matrix structure. If you have several channels, you might have several rows, if you have several samples, you might have several columns. About the sitmulations, you will find all the information at the stimulation codes...

Re: Stimulations modification

Dear Lorena, the purpose of the display cue image is to present image stimulus based on the actual stimulations that come to the box ; what you want is a feedback box now, something close to the level measure box I believe. The display cue image is not able to provide feedback, the level measure is ...

Re: ModularEEg Driver

Dear Lorena,

indeed, the OpenEEG driver does not have a dedicated DLL file. Its code is statically linked with the acquisition server application.

Can you see the driver in the acquisition server combo box as shown on this screenshot ?

Yann

Re: ModularEEg Driver

Dear Lorena, the OpenEEG driver is built in the standard installation of OpenViBE under the name OpenEEG Modular EEG P2 . It uses the P2 protocol so if your device/firmware uses the P3 protocol, it may not be compatible. Be sure to double chek the COM port used by your device to set it up properly i...

Re: Acquisition with EGI GES300 via AmpServer

Dear augustynowicz,

you indeed need to acquire the AmpServer Pro SDK for EGI, the standard AmpServer won't expose the data in realtime.

Hope this helps,

Re: Procomp+ support?

Dear salamandyr, I'm sorry I did not make it clear about the license issue. The point is TT don't want their devices to be used for clinical application with third party software. They made their SDK license this way and this implies a restriction of the use that can be made of their SDK. On the oth...

Re: Procomp+ support?

Dear salamandyr, thank you for this question. The Thought Technologies devices are not yet supported by OpenViBE. Their SDK license has restrictions on the application that can be built with it. Among these restriction is one regarding the clinical applications. This is not compatible with the LGPL....

Dear sumitsoman, thank you for reposting publicly as advised, this will be helpful for other readers. On one hand, the Graz visualization box is not (very) flexible (at all).

And indeed, there has been much more contributions for the acquisition server than for any boxes so far. This said, it is not a big chal...
