Ocean: exporting internal circuit signals taking more than 1h

The following working code saves the voltage of all signals from a circuit in a text file:

I0.U94.net0158 0.999999
ADDR_OUT\<0\> -3.61176e-07
ADDR_OUT\<1\> -3.68596e-07
ADDR_OUT\<2\> -0.000613136

The problem is that this script saves a lot of junk like the following (with the .gi internal transistor signals):

I0.U1_RES_reg_2_.GNI 3.04658e-07
I0.U1_RES_reg_2_.MN1.gi 1.00009
I0.U1_RES_reg_2_.net019 0.999994 

In fact, from ~80k lines, more than 55k lines are with "junk" signals.

Question 1) Is there a way to avoid these ".gi" signals from transistor nodes?

Question 2) It's taking more than 1h to export these ~80k signals after the simulation. Is this normal?
