Dear Siesta users,

I followed the graphene nanoribbon tutorial 
(http://dipc.ehu.es/frederiksen/tstutorial/index.php/Zig-zag_graphene_nanoribbon)
 and got the transmission spectrum data in output file. I plot it out but 
somehow the curve is shifted and magnified, i.e. the answer's curve for defect 
zigzag nanoribbon is between 1 to 3 and centered at 2 (Y-axis), but I got 2 to 
6 and centered at 4.

It seems there is a factor of 2, but I followed exactly the same steps from 
tutorial and don't know why there is such a disagreement. Any suggestion is 
welcome and appreciated, thanks!
 
Best Regards,
Z. Q.
