Hi,
Is it possible to draw k-resolved transmission spectrum from the output file of tbtrans?
If it is possible is there any utility code required for this?
Thanks

The sisl tool enables you to do this. Please see http://zerothi.github.io/sisl/docs/latest/api-generated/sisl.io.tbtrans.tbtncSileTBtrans.html#sisl.io.tbtrans.tbtncSileTBtrans.transmission

and specify kavg=<integer> and loop over k-indices.

This, for instance, would loop over different k-points and print the k-resolved transmission to the stdout

import sisl as si
tbt = si.get_sile('siesta.TBT.nc')
for ik, k in enumerate(tbt.k):
    T = tbt.transmission(0, 1, kavg=ik)
    print(T)

Can you help with this problem?
