DPARSFA error calculating DegreeCentrality

Hello,

I,m recieving the following error while calculating Degree Centrality on two sample data in Matlab 2019a:

Computing Degree Centrality...Error using file_array/subsref>subfun (line 110)
Requested 197x233x189x250 (16.2GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and
cause MATLAB to become unresponsive. See array size limit or preference panel for more information.

    t = subfun(sobj,args{:});
 
Error in file_array/numeric (line 13)

197x233x189x250

What's the voxel size of your data after normalization?

the voxel size of my images are 1*1*1 after normalization

That's too much for your computer. You don't need to relice to 1*1*1 as your data acqusition has much larger voxel size.
