for updating the MUD filters

Hi Gerv,
What I am trying to do is write an adaptive algorithm for the P300 signal which would automatically update the MUD filters.
This is the reason why I am looking into finding where I can get continous value of the voltage which is written in the .dat file.

Thanks,
Janki.

Where do I get the value of the continous signal

As I tried printing to the file, the signals[0] in the TTask doesnot seem to be giving the continous value of the signal. If I need the continous value of the signal where should I be looking into.
Thanks for your help Gerv.

Janki.

P3-Speller Target-NonTarget Signal values

Hi, I wanted to know how to get the signal values of the target and the non-target separately. I wanted to know the values in realtime at the end of the signal processing. Using the BCI-frequency tool we get the values of the target and non-target. Is there a way I could directly obtain these values...

p3 - speller using only 6 icons

Hi, I changed the existing P3speller to work for 6 icons in a row. I just flash the columns. The problem in this transformation is that when the averaged signal on ERP graph shows up, it does not show up for the last 6 columns. What do I need to do, to fix this problem. For example in the P3speller ...

a further question

Thanks gerv for the link, I'll look into it. I have one more question, what I have tried to do is extend the P3speller code to have a single row and 6 columns instead of the 6x6 matrix. The way it calculates the selection is by predicting just the column with the highest value rather than the inters...
