The output from the build script gives a max distance of 104.7 Å. 
With a 15 Å padding, that's a 120 Å cell. Truncating that gives:  
same residue as (-x-y-z<103.923 and -x-y+z<103.923 and -x+y-z<103.923 and -x+y+z<103.923 and +x-y-z<103.923 and +x-y+z<103.923 and +x+y-z<103.923 and +x+y+z<103.923 and x < 69.282 and x > -69.282 and y < 69.282 and y > -69.282 and z < 69.282 and z > -69.282 and noh)
