How to prepare file "stran_list"(step 01) ?

Traceback (most recent call last):

File "/home/Project2/pan-genome-analysis/scripts/pangenome_computation.py", line 163, in process_clusters
strain_list=self.strain_list,
AttributeError: pangenome instance has no attribute 'strain_list'

I want to use strain's information with my own format(not Genbank format), so I only input extracted strain's sequeces and run step 5,6,7,8,9,10, but I don't know what's the step1 meaning. How should I prepare "strain_list" , and how the file "geneID_to_description.cpk" output or I should prepare it by myself?

Thank you!
