'Sox9_Example/{}_{}_{}.bed' is missing

Hi,
Very cool tool, i tried run the example codes with example data, most of the codes worked well, i got an error at end of the analysis:
TypeError Traceback (most recent call last)
Cell In[20], line 15
13 # Run METALoci
14 print("Running {} on {} dataset for {} signal data...".format(gene,dataset,sigdata))
---> 15 MLs(gene,region,gender,dataset,covcor,reso,midp,sigdata,hicfile,sigfile)

Cell In[19], line 287, in MLs(gene, region, gender, dataset, cf, reso, midp, sigdata, hicfile, sigfile)
285 metaloci_data = pd.DataFrame()
286 if (HHdata.unary_union.geom_type == 'MultiPolygon'):
--> 287 for i in range(0,len(HHdata.unary_union)):
288 ml = HHdata.unary_union[i]
289 ids = GetPointIds(coords,ml)

TypeError: object of type 'MultiPolygon' has no len()
the i checked the code, and i didn't find Sox9_Example/{}{}{}.bed file, could you please also provide this file?
Thanks in advance!
Best,
PF
