I used VNL-ATK 2015 to calculate the transmission spectrum ,but i don't understand the export data of the transmisison spectrum .What does the data in Line2D(_line0,1,2,3,4,5,6) mean?It is extraordinary to see that data corresponding to line6 only has two lines(see the attachment [transmission in ATK]).In addition ,what code should i write in the input py script to get the transmision data averaged by K-point (see the attachments [input.py,transmission in siesta]).
