We didn't mention this in the article, but there was a column of 1s in the X matrix that would represent the intercept. This doesn't matter though as the signal was normalized in real time with respect to the mean and standard deviation. One other issue- whether the intercept is 0 or not is not a ma...

Normally a spatial filter is helpful and you might consider evaluating one (e.g., Common average or surface Laplacian). The bias due to the skewed distribution of signal amplitude values can be reduced by a log transform as you suggest. See the expression filter (http://22.214.171.124/wiki/index.php/U...
The lms file should contain values when WeightUse = 1. Perhaps there is some other problem. Try running it with WeightUse = 2 (perhaps without actually having a subject attached). The adaptation also depends upon the values in row 7 of the Target Position Matrix (adaptcode). If this value is 0 (or s...
RJB does not support weight adaptation. In fact, RJB is not currently being updated since D2Box can do the same functions and more. There is no way to specificy the code for adaptation in RJB. This is part of the target definition in D2Box. Parameter fragments are available to parameterize D2Box so ...
