Re: How to configure online prediction

So I believe I have to edit the bci_process function, from here I seem to be able to determine what happens based on the calculated prediction. But can I output to a port to interact with an external device? I realize this seems to relate to BCILAB, but there doesn't appear to be a specific BCILAB f...

How to configure online prediction

Hi, I am currently using a research edition Emotiv epoc coupled with BCI2000, matlab and bcilab. However I am stuck with regards to configuring the online analysis and using the output prediction. I had some issues with the online session crashing in a previous thread, this seems like it was due to ...

Re: BCI2000 v3.6 beta test

Thanks for the update. I am still having the same issues as described in this thread though, http://www.bci2000.org/phpbb/viewtopic.php?f=1&t=3211 The beta versions just crash every time for me. The full release is more stable as expected but I still have an online prediction issue. I don't know if ...

Re: Terminating SignalProcessing module

Does this dimension error relate to the one that was corrected in the MatlabFilter?

Re: Terminating SignalProcessing module

I managed to catch a glimpse of the above mentioned error and crash. The message appears to say;

BitmapImage dimension mismatch
function: BitmapImage: DimensionCheck()
C:\BCI2000.x32\src\shared\types\BitmapImage.cpp
line 109
Aborting Operator

I'm unaware of the above directory?

Re: Terminating SignalProcessing module

You were right about the previous error, I tried both BCI2000.x32 and BCI2000.x64 and both were able to get to the 'set config' stage at least. However on setting the config both caused BCI2000 to crash with no error. An error message is shown but instantly closes before it can be read or even scree...

Re: Terminating SignalProcessing module

pbrunner, That was good timing, thanks. Unfortunately though it seems to have caused other problems. I tried using the BCI2000.x32.extensions R5253 version which gave the following error message before even getting to start the experiment. 2016-02-23T09:49:41 - BCI2000 Started. 2016-02-23T09:49:41 -...

Re: Terminating SignalProcessing module

Not entirely sure I know what I'm doing. I commented the lines out but not sure how the build process is working. Think I'll wait for a beta release, the ticket mentions it's fixed in R5241

you can give it a try. Just remove the two lines of code and recompile.

Regards, Peter
A rather novice question but, what program do you use to edit and recompile the executable file?

Re: Terminating SignalProcessing module

Jewatts, I wanted to give you an update on the issue that you have experienced. I have started to look at the MatlabSignalProcessing module within BCI2000 and have isolated the first bug. We will tackle this within the next two weeks, to get the MATLAB functionality back up and working. Once the co...

Re: Terminating SignalProcessing module

No problem, here it is. I was going to do that originally but thought it would be too big a file.

Re: Terminating SignalProcessing module

Jewatts, thanks again for isolating the issue. Can you do one more thing to make things easier for us to debug the issue? Specifically, can you please create a minimum working example that exhibits the issue. In other words, use the SignalGenerator source module instead of the Emotiv source module ...

Re: Terminating SignalProcessing module

Well I've narrowed the issue down to the bci_process function within bcilab now. I can now load up bci2000 from my small batch file, this also loads bcilab 1.0 (or 1.01, both have the same issue) and matlab command window. Once all loaded I can click 'set config' and it still continues to set up fin...

Re: Terminating SignalProcessing module

Thanks for the reply, I'll try v3.6 when I'm next in the lab. As for the matlab functions, I haven't written any of them they are either from bci2000 or bcilab. The batch file effectively loads up bcilab and signal processing before allowing you to set the config from bci2000. I'll try various versi...

Terminating SignalProcessing module

I am having an issue running my online BCI experiment. The offline runs fine so I think the issue is the signal processing. This is my setup: windows 7 64bit matlab 2013a 32bit latest BCI2000 install BCILAB 1.0 (and 1.01, both required due to difficutlies with newer versions) The experiment is start...
