Hi Zeynab,
the *.TSHS files are built in a previous stage, during the Electrodes
calculations (which is actually a pure SIESTA calculation with a high
number of k-points in the transport direction), and then used when the
Scattering Region calculation starts to describe the electrodes, but it
is true that they do not change anymore at this last stage.
regards,
Carlos

In fact, TSHS file isn't used for a continuation run.

A continuation run does not know what the previous runs Scf count is,
so it starts over.
If it says it has read in the TSDE file, then it is a continuation run.

So I would guess nothing is wrong and it actually behaves as expected. :)

restarting, you must check that you have the *.TSHS and *.TSDE files
from the previous run in the directory where you are going to restart
TranSIESTA. By the way, TS.SaveHS is true by default, so you should
find the *.TSHS from the previous run unless you set up TS.SaveHS
false previously.

however, the electrodes can be different and therefore you will have
two different *.TSHS files; one for the left electrode and and another
for the right electrode.

open boundary conditions and bias potential.
