open your input file and check the atomic positions. there is something
wrong there. maybe you forgot to specify the atomic species, or something
else the code expects to find. I typically get this error when I fail to
append the file with positions. I'm not sure this is the error you get if
you indicate a wrong number of atoms. check that too.

hope this helps.
