Hello, In reference to BioSemi's active electrodes, the original poster asks the question "Why does the impedance across the gel/skin/electrode interface no longer matter?" I've been reading through the forums and notice that there are many descriptions about why 'electrode impedance' is negligible ...

Thanks very much for your reply, Coen. I have since explored LabView's library of subVIs, and have been able to accomplish my original goal by avoiding filtering and instead performing power spectrum analyses for each channel.

Hello, I am trying to take the 2D array of samples from 64 EEG channels in the ring buffer, and process these to determine in real-time the respective power of delta, theta, alpha, beta, and gamma brain wave activity. I am attempting to do this using bandpass filters within an auto-indexing for-loop...

Thanks Paul. It seems that no matter how 'BioSemi-Labview_DLL.framework' is being referenced (e.g. referring to the structure itself; referring to its containing folder; using '/', '\', or ':' as separators between subdirectories), a message immediately comes back saying "The file selected is not a ...

Thanks for your continued assistance, Coen. I had a chance to try the Labview_DLL_SyncTest in the lab yesterday. I wasn't clear from within the INSTALL-MAC.txt instructions where to 'type "./Labview_DLL_SyncTest 0" to start the test program.' I tried this in the Mac Terminal interface nonetheless, a...

Hm, yes I am working in a different OS: OSX 10.6 (32-bit). Would this create a compatibility issue?

Thanks,
Matthew

Thanks for your response, Coen. I have downloaded the ActiMac folder from the link provided. Upon opening "ActiView700-Mac-Rev15.vi" in LabVIEW 2010, a list of 15 errors show the following Library Function Nodes as "Library not found or failed to load": READ_POINTER OPEN_DRIVER_ASYNC CLOSE_DRIVER_AS...

Hello, I'm looking to further develop ActiView using my version of LabView 2010 for mac, but seem to be faced with some obstacles. Upon starting up any of the ActiView sourcecode programs, LabView was originally unable to find Labview_DLL.dll or the following files in the <vilib>:Utitlity:inputDevic...
