Dear all: I am trying to calculate the optical properties of graphene.
I have the .EPSIMG file and i want  to calculate different optical properties
out of it.
i used the command input < Systemlabel.EPSIMG but  siesta asked for length ,
 diameter and position of antenna elements to be written in 
a file that i should specify
i think there is something wrong because i have no antennas 
i will be thankful if someone help me
with regards
