[Eeglablist] ICA decomposition and PCA

Dear group,
I was running ICA with the algorithm runica and the option´extended´1 (by
default) but I have noticed that in case of using average reference (as I
do in one of my group of subjects) It's better to use ´PCA´ number of
electrodes-1.  So I would use runica  ´extended´1 in one group and runica
´PCA´64 in the other one. Is it right? In affirmative case, do I have to
write ´PCA´ 64 in the edit box of the "Commandline options" ?

Thanks you in advance,

Esther
