About epileptogenicity map and displaying SEEG recoodings: Error in baseline normalization

Hello,

I have a problem during displaying SEEG recording to make epileptogenicity surface. When I try to do the baseline normalization by Z-Score transformation method I get this error message.

I think that I was doing the same way as other times. I was following the tutorial when I selected the time-frequency files as multipaper files, but it´s possible I am doing now something wrong.

Thanks for the help

Be sure that you are selecting the same type of data in both sides (FilesA and FilesB)

Yes, I used the same file data (multipaper of Baseline and seizure onset)
