I have performed GCD for supercapacitor but not getting proper curve, something is wrong. I have attached the recorded file. Please help to what parameters I have to set and how to set.

My question are:
1) how to set the Current values (A/g) in Charge-Discharge, What is the Procedure and Step wise.
What is the Procedure in Charge-Discharge please tell me, step wise.
Please Any body use/ know the NOVA software help me Please Researcher and Scientist.
find the highest value of current from cyclic voltammetry at different scan rates, then divide the value by the mass of the active materials loaded on the working electrode to get (A/g). Use the procedure attached and put the current value not the (A/g).
in the procedure, you find two icons named as set current, put the value in the first one as a positive value and in the second as a negative.
the second file illustrates how to put the potential values.
Dear Safa...
I have tried so many times to record the charge discharge but couldn't reach to the ideal GCD curve. Your Nova file is latest and I couldn't performed from it as I have Nova 1.10.
Can you please help me more to get the proper GCD curve.
Thanks
Steps for GCD:
1.Take CV from 10 mV/s to 100 mV/s
2. See the current range
3. select chronopotentiometry and set the current , required time and cut off voltage and run.
It seems that the discharging time is fixed to few seconds (around 5 s), try to increase it to 5000 or so. Thus the curve will continue after 60 s.
