The description of the neuron model gif_psc_exp states that the adaptive current q_stc is given as a list of nA. I think this has to be pA.
I can not find a conversion between nA and pA in models/gif_psc_exp.cpp or models/gif_psc_exp.h, but the sum of all adaptive currents gets added to the parameter I_e which is given in pA.

nest-simulator/models/gif_psc_exp.cpp

Line 357 in 6bed7e3

S_.V_ = V_.P30_ * ( S_.I_stim_ + P_.I_e_ - S_.stc_ ) + V_.P33_ * S_.V_ + V_.P31_ * P_.E_L_

S_.V_ = V_.P30_ * ( S_.I_stim_ + P_.I_e_ - S_.stc_ ) + V_.P33_ * S_.V_ + V_.P31_ * P_.E_L_
+ S_.I_syn_ex_ * V_.P21ex_ + S_.I_syn_in_ * V_.P21in_;
