Hi Carlos,
Thanks a lot for the answer. As you said I had a look at the last lines of the
OUTPUT.fdf for the first run and the first lines of that ofcontinuation run. I
think the energies aren't that much close. Would be thankful to let me know
your idea about it:
Here I copy the last lines of the first run:

I also see the following options in the OUTPUT.fdf of Continuation run, which I
guess they confirm it is really a continuation job:
New_DM. Step: 1Initializing Density Matrix...
ts_iodm: Reading Density Matrix from filesTRANSIESTA: Continuation run

Zeynab,
and one more thing, in order to check that the TranSIESTA calculation restarts
properly, you should look at whether the energies, convergence of the density
matrix and Fermi energy for the first SCF steps are very close to those of the
last SCF steps of your previous run. The SCF counter simply starts from 1 again
as Nick points out.

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. :)
