changing the location of netlist creation in loop

Hello

Please refer to the link below:

https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/35371/creatnetlist-with-ocean-in-a-specific-directory,

I am trying to do a similar thing i.e. changing the location of netlist creation. I did set the "startup" env var before the simulator call but I have to run the createNetlist command multiple times and in different directories ( I am changing the directory as I want to change models and then simulate the netlist and do not want to overwrite). So, in that case, would it be a good idea to set this variable in every iteration?

Please guide me on this. 

Also, I notice that if I interrupt my skill script(Ctrl+C) before it completes itself (since I have a lot of cases and it takes time) and then if I rerun it after making suitable changes, I get the following error :

 *Error* (Default-reader-method) generic:asiGetName class:list

Could you help me understand the reason for this?

Regards
