Re: CSV file writer - sampling frequency issue
Hi JelenaJ, If matlab sends data at 512Hz, a time based epoching (setp=0.1s, duration=3s) should create chunks of 3 seconds every 0.1 seconds of the signal, but it should not change the sampling frequency. You can confirm it if you create a scenario with just the acquisition client, a time based epo...

Re: TCP TAGGING
Hi Marios, Sorry for the mistake in my previous message, the biderectionnal game box is not yet in the development branch. To use it now, you need to build OpenVibe with the following branches for each repo: - meta: development - sdk: development - designer: development - extras: 61-feature-bidirect...

Re: TCP TAGGING
Hi Marios, The Brain Hero unity app is at its early stage of development, and not integrated in OpenViBE yet, so you will not be able to use it until a future release of OpenViBE. The Hello Bidirectionnal box is present on the development branches of the code base on our gitlab . You need to checkou...

Re: Issues with classifier processor box running p300 speller
Hi, Indeed a bug was found on the P300 speller. A fix has been applied to the development branch, so if you have already built OpenViBE yourself, you need to: - Checkout development branch on all repositories (meta, sdk, designer and extras). - Run install_dependencies script again - build. Then you...

Re: Errors with User Account
Hi, To follow up on my previous message, it appears that no scenarios are polluted with my user path finally. My user path appears because openvibe prints the file and line at which the error appends when an error appends. As openvibe was built on my machine, it naturally prints the path to the erro...

Re: Errors with User Account
Hi,
It seems that I polluted some scenarios when updating them before the last release. Apologies for this.
I will have a look at this. What scenario did you try to run ?
If you can provide a more complete error log, that would be very appreciated.
Thanks,
Thomas

Re: Building on Ubuntu
Hi Bartlomiej, I think the problem comes from your python installation which is missing shared library. What Linux distribution are you using ? Did you compile your python installation from source, or installed it with package manager ? If you compiled it yourself, at configure step, did you enable ...

Re: Designer doesn`t start.
Hello, Yes, it is possible to fix this. Maybe the version of Python3 you have installed is not the right one. Please see the following page for version info: http://openvibe.inria.fr/tutorial-using-python-with-openvibe/ When installing python, make sure to tick the box "Add Python to Path", in order...

Re: Help / advice needed for PLV (Hilbert, connectivity measure, ...)
Hi, Yes we are aware of issues with the connectivity measure box. Unfortunately we do not have a fix at the moment. We are currently working on this box and should be able to provide a stable version in a future release. Although the release containing the fix will not be before 3 to 6 months, the f...

Re: Problems compiling gtec usbamp driver
Hi, Looks like there is a problem with the static_cast. An easy way to overcome this is to edit the file /home/brix07/openvibe-3.0.0-beta-src/extras/contrib/plugins/server-drivers/gtec-bcilab/src/ovasCDriverGTecGUSBampLinux.cpp and replace the static casts with C-style casts. For example, replace: m...

Re: What does samples per buffer mean?
Hi Naomi, When a box sends data, it sends a certain amount of samples at a time in a buffer. The "Samples per buffer" setting defines the amount of samples the box should send in one chunk. The GDF reader box will extract the sampling rate from the GDF file, and send as many buffers (chunks of data)...
