A possible solution could be to specify by hand all the k-points you need when you calculate the TSHS file with transiesta after the siesta runs.
Thus I add to the mailing list also this question:

Can you give in input in Siesta the coordinates of each k-points by hand ?

Hello all,

Is it possible within transiesta to calculate the transmission at certain, user specified k-points?

I have a system where most of the transmission takes place at a small region in the surface brillouin zone. Hence instead of sampling the whole BZ for the transmission, I want to confine my sampling to a small area around a single, high symmetry K-point. Actually, it is something similar to what you would do when computing the band structure in a siesta run.

The option of using a Monkhorst-Pack Grid, or kgrid cutoff for this problem is not great, and I don't find in the manual a third option. Does anybody know of an alternative?

I would really appreciate any help with this problem.

Thanks a lot!
