Thank you Nick for your good answer.
I have found two parameters not explained in transiesta manual which I do
not know how they could affect the results, they are:
TS.RealContour.Emin
TS.RealContour.Emax

Nick I have asked you before about the convergence tests in transiesta and
you have told me about the paper, but unfortunately I did not find what I
looking for.

Regards
