Just the wrong positions
Co on 1/4 1/4 1/4 (second position will be generated automatically)
Ti on 0 0 0 
Al on 1/2 1/2 1/2

Do not forget to read my papers !

Ciao
Gerhard

Dear Wien users


   I  am working on Co2TiAl Heusler alloys L21
strucutre Lattice constants 11.018 a.u. space group
225Fm-3m
with the (0,0,0) &(1/2,1/2/1/2) for Co
         (1/4,1/4/1/4) for Ti
         (3/4,3/4/3/4) for Al

my question is using structGen (Please see below my
struct file) I get different position (why) 
(please  correct me if my stucct file  is wrong)

 Thank you for your advice
