I'm very new to PCA analysis of ERP data. I tried to generate the amplitude report for a principle component by using AutoPCA in the PCA toolkit. But I got the following error message in the MatLab
Starting AutoPCA. Window size and adjoining samples option for peak measures ignored.
There are 16 factors that meet the minimum variance criterion of: 0.005.
Undefined function 'iscomplex' for input arguments of type 'double'.
Error in ep (line 5348)
if iscomplex(EPdata.data)
Error while evaluating uicontrol Callback
I'm not quite understanding what this message tells about. It seems that it reads the PCA file well but has some problem in generating the txt file in my case? What could I do?
I'd appreciate very much for your help!

Sorry I forgot to mention the version I'm using. It is PCA toolkit 2.45. And the AutoPCA was based on a temporo-spatial file.
My bad! I'll send you a fix tonite. I'm planning on releasing a new update this weekend which will include this fix.
