Dear Fieldtrip-users, 


We are not able to use function ft_selectdata after applying head movement
correction using ft_regressconfound. The error that we get is the well-known
index exceeds matrix dimensions. 

It is due to the fact that the size of x is incorrect, it doesn’t correspond
to the number of trials but is 7 which is the number of regressors in the
beta variable that is created by using ft_regressconfound. 

There is a simple way to solve it and this is deleting the field ‘beta’
before running ft_select data. 


My question is, just to be sure, the variance is regressed out by using
ft_regressconfound so the beta variable is not needed in any further step

Maybe this is also something for the debug team? Thus that ft_selectdata
runs after running ft_regressconfound. 



Dr Conny Quaedflieg
