File problem request in bias correction

/project/mchaisso_100/cmb-17/vntr_genotyping/rpgg2_k21_84k/hgsvc/clinic/cdbg/v1/ki_tr.ccki_tr.pickle
How did you make this file?
ki:     index of the motif in our database; "-1" if the variant is TR length
So what does "ccki" mean?
Is the file mentioned above the file "metadata/ danbing_aln_outport.tr_kmers.metadata.txt.gz"?
