Dear Wien2K,

                I am trying to do AFM calculations. I followed the user
guide to set the AFM calculations. I got some error. Here i am giving the
step by step information.

1. first i run init_lapw up to lstart in magnetic case. After that i copied
my case.struct to case.struct_supergroup.

2. I again run init_lapw in the same magnetic case like bellow.

-----> do you want to perform an antiferromagnetic calculation ? (N/y)
y
I hope you have        flipped the spin of the AF-atom
                       made zero spin for non-magnetic atoms
in case.inst
-----> do you want to continue or edit case.inst ? (c/e)
c
>   afminput    (12:03:08)  case.struct_supergroup present
 The super and subgroups are KLASSENGLEICH
 You must specify a translation vector which transforms the
 spin-up into the spin-dn atom (e.g.: 0.5,0.5,0.5 for AFM bcc Cr)!
0.5 0.5 0.5
0.0u 0.0s 3:03.38 0.0% 0+0k 2064+96io 6pf+0w
You can now use     runafm_lapw   for scf
BUT  PLEASE  NOTE:  AFMINPUT and CLMCOPY  are NOT WELL TESTED
You must test your results with an unconstraint  runsp_lapw  afterwards
and recheck the rules generated by afminput
init_lapw finished ok

3. After this i run "runafm_lapw -ec 0.000001". But i got the bellow error.

xxxxxx at xxxxx:~/xxxxx/yyyyy/xxxx/xxx$ runafm_lapw

May i know how to resolve it..

Thank you very much in advance....
