It seems to be the problem of the memory space because my %CPU is over 90% when running 3dTcorrMap :(.
It's really impossible for me to update my computer recently, so I guess I could import my data into the MATLAB to finish this analysis, but my code couldn't work.
Here's my core command in AFNI.MATLAB:
"[x_size,y_size,z_size,TR]=size(Vmask);
TcorrMap=zeros(x_size,y_size,z_size);
for x=1:x_size
for y=1:y_size
for z=1:z_size
voxel_time=squeeze(Vmask(x,y,z,:));
if unique(voxel_time)~=0
TcorrMap=corr(Vmask(x,y,z,:));
end
end
end
end"
Is there any problem in my way of using this "corr" function?

Best regards,
Sue
