Re: Error building a project in Windows 7 64 bit

I was finally able to get this work. Here is what I did just in case anyone faces the same issue. Just FYI, I am using Cmake version 3.0.2, and "Building against a Qt distribution outside the BCI2000 source tree" 1. Run cmd.exe as an administrator and cd into the \build directory. 2. Now run "Make V...

Re: 0xc0000005 :(

I figured out a workaround for this. If I run BCI2000Shell.exe before invoking the batch script, I do not get this error. So this is kind of a hack. I am still trying to understand why it's happening though.

Re: help for removing artifacts

Hi, There are several ways to deal with artifacts. You can use simple threshold/frequency based algorithms that can be implemented in real time fairly easily. You can do more complicated processing like Independent Component Analysis (ICA) offline. The EEGLAB matlab toolbox provides useful tools to ...

Re: 0xc0000005 :(

Hi guys, This error has come to haunt me again, except this time its even more weird. I get this error only if I run a batch script. If I manually load the modules in the Operator everything works fine. But if I run them in a batch script it gives me the error. I tried deleting the Operator.ini file...

Re: Need help with Operator Scripting

I figured out a way to do this. Using GET STATE commands it is much easier to do what I wanted to do. I did not notice them earlier. Everything works fine.

Need help with Operator Scripting

Hi, I wish to run a sequence of applications automatically by simply running a batch file. Here is the general flow: Start Task 1 --> Wait until it is over --> Start Task 2 ... and so on I am trying to do this using Operator Scripting. I am aware that I can set "Running" to 0 or 1 from the batch scr...

Re: 0xc0000005 :(

VOILA... Deleting Operator.ini does work. I wonder why that happens though. From what I understand, Operator.ini, keeps a log of changes in the Operator configuration, visualization etc. I remember playing with a lot of 'Config' parameters and they are all logged in Operator.ini. Besides the positio...

Re: 0xc0000005 :(

Hi, I have run into the same error today. Everything was working fine and suddenly it gave me 'Unhandled Win32 exception 0xc00000005: ACCESS_VIOLATION Terminating Operator Module'. Initially I thought there was a bug in my application but it still gives me the same error if I run: Operator --> Signa...

Re: QTimer working slow with BCI2000

I get your point now. I synchronized with Process() and now it works fine. I also replaced the QTimer with QTime to handle timing.
Thanks for the help.

Re: QTimer working slow with BCI2000

Hi Juergen, Thanks for your reply. I am using the StartRun() and StopRun() functions in BCI2000.

Hi, We are trying to study the changes in EEG power levels with different levels of Cognitive Load. For the same, I am trying to develop a new Application in BCI2000. It is the n-Back Test which is widely used to impose Working Memory Load on the subject. So far I have developed the nBackTest same i...
