P300GUI was suddenly generated an error.

[okasachi]

Hi,

I've used P300GUI to make a parameter file for BCI2000 Linear Classifier.
The following error was suddenly caused though it had worked well last month. It moves well by an old dat file. However, I don't change anything in the measuring method.
Is anyone who understands the solution, please give me the reply.

Regards, sachiko



??? Undefined function or variable "coderow".

error ==> P3Classify at 110
tar=charvect((NumMatrixColumns*(coderow-1-NumMatrixColumns))+codecol);

Sachiko,

P300GUI will be replaced with a new tool in BCI2000 v3.0 that has the same functionality. Could you please post your email address so that we can send it to you?

BCI2000 is evolving. It's really wonderful!

The problem above was solved by reinstalling BCI2000. Now BCI2000 and P300GUI work well.
When the error occurred, BCI2000 was newest one and I did not add any change at that. So, I couldn't know why the error was out. But solved.

Thanks to Dr.gschalk, now I can use the P3classifier comfortably. Thank you.
