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.
