Dear Prof. Blaha,

                        Thank you for your response Sir. I have been able
to form single monolayer of Graphene. However while starting I get an
unusual error as can be viewed by STDOUT;
/usr/local/bin/btp2/hup: Not a directory.
STOP  LAPW0 END
grep: No match.
grep: No match.
grep: No match.

>   stop error

Please advice. I am attaching the struct file in this email.
