[Wien] error about elast constants calculation

[Shaorui Sun]

Dear all:
     I try to calculate elast constants, and when I run the init_elast program, an error comes out as follows:

********************************************

next is setrmt
Automatic determination of RMTs. Please specify the desired RMT reduction 
compared to almost touching spheres.
Typically, for a single calculation just hit enter, for force minimization
use 1-5; for volume effects you may need even larger reductions.
 
Enter reduction in %
5
  please specify nn-bondlength factor: (usually=2)

Do you want to accept these radii; discard them; or rerun setRmt (a/d/r):

who could tell me what is the matter, and how to resolve it?
