Hello all,
Recently Ive been trying to learn the SIFT toolbox and everything has been running relatively smoothly until I have tried to validate my MVAR measures and it gives me the following error.
>> [ whitestats, PC, stability] = pop_est_validateMVAR(ALLEEG,0,'whitenessCriteria', {'Ljung-Box','ACF','Box-Pierce','Li-McLeod'})
checking condition ...
Using 50 lags for covariance estimation.
checking condition ...
Using 50 lags for covariance estimation.
Index exceeds matrix dimensions.
Error in est_checkMVARWhiteness (line 132)
residuals =
est_mvarResiduals(squeeze(EEG.CAT.srcdata(:,g.winStartIdx(t):g.winStartIdx(t)+winLenPnts-1,:)),
...
Error in pop_est_validateMVAR (line 232)
whitestats = est_checkMVARWhiteness(ALLEEG(cond),MODEL(cond),typeproc,g);
>From having a rough look at it, it would appear that the part of the code that does:
g.winStartIdx(t):g.winStartIdx(t)+winLenPnts-1?
generates a number greater than the number of columns in EEG.CAT.srcdata
I dont really understand what is going on.
