Hi Nguyen,

you have to exclude non-spherical particles from the loop:

a=open('radius.txt','w')
for i in O.bodies:
  if not isinstance(i.shape,Sphere): continue # after this line, only
spheres continue the loop and are written to the file
  a.write('%d %f \n'%(i.id, i.shape.radius))
a.close()

cheers
Jan
