Hi Sandeep, I don't know which version you are using. For Siesta 3.2, the second column in a * .AVTRANS file is T(E), namely transmission probability. Cheers!

I think u may get G directly from one of outfile with extension .AVTRANS's second column marked as Trans[G0].

    yes, i use tbtrans but the out file contains the value of current
    for each voltage bias
    my question is, G is directally calcutated and printed in one of
    ouput files or i should
    write a script to differenciate dI/dV.

    at 0 bias G=(e**2/h)T(E)

    You can use the tbtrans post processing code

        Dear all,

        in many paper, we can see that we can present the conductance
        G=dI/dV
        my question is how to get G from Transiesta calculation at 0
        bias and under
        finite bias voltage?

        best
