This depends on the version of tbtrans used.
In the version shipped in 3.2 it is the sum of both spins (hence you get
double the current for spin-symmetric systems).
In the latest version (siesta-trunk-458, Util/TBTrans_rep) it is current
carried per spin, so they should be the same, as you would expect.

Hi dear transiesta users:
I am transiesta user.I don't know why? when i calculate current in Spin
Polarized mode for pure non magnetic structure the down current is doubled
rather than up current .I think it is not true.T(E) (transmission function)
respect to E for both up and down current is exactly same, but current are
different, How knows about the problem to help me with this.
thanks in advance
best regards
Mostafa
