Doubt about 2D and 3D visualizations

Post by BrainSup »

Hello,

I would like to get a step-by-step in order to get a 2D and 3D views of the EEG signal using ActiChamp. Apparently everything is connected and sending information, but after we follow the instructions from tutorial 4, nothing appears on the window.

Thank you,

Silvia

Hi Silvia,

If there is a problem related to the actichamp acquisition, I can help !

Do you manage to see the EEG signals in a simple signal display ?
I mean, by using just 2 boxes: Acquisition Client + signal display.

As for the 2D and 3D topographic display boxes, I won't be very useful as I do not use them.
I think they need the channels names to be able to position the electrodes on the 3D /2D models, so you may want to check if all channels have a name in the acquisition server.

Dear Laurent,

Nothing appears on the screen even in this basic test. What should I do?

Thank you!

Dear Laurent,

I wonder if it is necessary to have a file with the x, y and z coordinates of the 32 channels cap. We have found a file with a 128 channels with this information, but we can not find one for 32 channels. Could you help us in this topic?

Thank you,
Sílvia Takey
