 Hi,
> So would not the total current be 3.325e8 * 2(for spin) * number of kpoints?
No, it wouldn't be. Since the average current is calculated by integrating all the contributions in the Brillouin zone as shown in Eqs. (5153) in PRB 81, 035116, you should not multiply the number of kpoints.
Each of 30 tran#_% files contain each transmission. If you would like to see the average one, you have to sum up all the contributions and divide it by the number of kpoints.

 Dear Sir,
Thank you very much for your kind help. I have gone through the paper, and found that the total transmission is an integration of the kresolved transmission. I have done that numerically, and there is some mismatch in the current result, I believe that is due to the numerical inaccuracy in my calculation (I used simple trapezoidal rule to integrate T(E)*(f1  f2) to determine the current).
Thanks again sir, it was very generous of you to answer my question.
Khalid
