Dear Users,
I have computed the optical properties of Si by using two program
input.f and optical.f in the directory siesta-2.0.1/Util/Optical and
the program is successfully run for Si but as I run the calculation
for LaAs the file e2.dat successfully generated but when everytime
when I type the command $./optical < e2.dat it is showing the
error as follows
Do you want to include a Drude term?
This is typically needed for metals
if yes: enter 1, if no: enter 0
What did you answer, 0 or 1?
invalid integer: read unexpected character
apparent state: unit 5 (unnamed)
last format: list io
lately reading direct formatted external IO
Aborted
Please guide me where I have done a mistake ?
