Procedure in Innovus common UI to generate scripts for placement

In an older Innovus version (152), the following lines were executed before placement. pnrflow/ was generated in innovus using "writeFlowTemplate -directory pnrflow"

• ./pnrflow/SCRIPTS/gen_flow.tcl all
• make init

In the new common UI, "writeFlowTemplate" is replaced by "write_flow_template" according to the manual (foundation flows guide). When I run "write_flow_template -directory scripts" it generates the folder scripts/ and scripts/flow with the following content. How do I proceed? Web search points to a script "scripts/run_flow.tcl" as the equivalent of gen_flow.tcl, but no such script is generated in my case. Basically I need to equivalent of "gen_flow.tcl" and "make init" mentioned above. 

scripts> 291: ls
design_config.template eco_config.template flow.yaml_template innovus_config.template setup.yaml_template
dist.py* flow/ flow_config.template metric_config.yaml
scripts> 292: ls flow
common_flows.tcl common_steps.tcl innovus_steps.tcl
