The logical indices contain a true value outside of the array bounds

I am trying to correct the voxel size and set outlier if fMRI activation maps and getting this error.

Error in voxel_size (line 38)

himg=aimg(mask>0);

As the error states, your logical indexing includes a TRUE value outside the size of that array. Compare:

V = randi(9,1,3)

V = 1×3

4 6 2

X = [true,false,true,false,false,false,false,false,false,false]

X = 1×10 logical array
   1   0   1   0   0   0   0   0   0   0

V(X) % no error

ans = 1×2

4 2

Y = [true,false,true,false,false,false,false,false,false,true]

Y = 1×10 logical array
   1   0   1   0   0   0   0   0   0   1

V(Y) % last TRUE is outside size of V

The logical indices contain a true value outside of the array bounds.
