I am trying to calculate PSD and Connectivity metrics for EEG data after computing sources. Everything works fine for surface sources but I am facing a problem when I am doing it for Volume sources as it gives me this error although I am using AAL1 atlas for both computations.
I went through similar problems like Error: scouts on volume grid, but surface sources and tried to fix it using the proposed ways although I still face the problem.
Kindly guide me what to do in this regard.
Sincerely,
Abrar
Yesterday it was identified by brainstorm as a surface atlas and today as a volume atlas so when I tried to compute PSD and connectivity for surface sources it gave me this error.
in the output file in the TF variable I get matrix which contain: TF : [Nr x Ntime x Nfreq] = [44675 X 30 X 7] or [4467 X 29 X 7]
I know that the first one are the connectivity pairs and the second one are the time points and the third are the frequency bands
My question is why I get 30 or sometimes 29 for the same folder? And how to get only 1 time point for the whole 60 seconds epoch?
@Abrar, please read carefully the error messages, you have reported two different errors, both have the same cause, the spaces for the sources and for the atlas are note the same:
A: In here, the sources were in volume, but the atlas was surface, thus the error:
Could it be that in some computation you are setting the beginning of the Time window to 0s, rather tha -0.003s?
This is the parameter Time resolution, in the shared screenshot, coherence is computed in windows 4s, and 50% overlap. If one time value is required, there is no time resolution, thus select None
P.S. For any question on a new topics, please create a new post.
