TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

Dear Developer,

Thank you for vcontact2. I tried to resume vContact2 after the diamond step using following command:

vcontact2 --pcs vcontact_diamond/vConTACT_pcs.csv --contigs vcontact_diamond/vConTACT_contigs.csv --pc-profiles vcontact_diamond/vConTACT_profiles.csv --db 'ProkaryoticViralRefSeq211-Merged' --output-dir vcontact_diamond --c1-bin /dss/dsshome1/0F/ra78zut/Alex/test/cluster_one-1.0.jar

‌

But I got the following error:

‌

‌

Really sorry for the silly question. I am not sure how to solve this. Any help would be appreciated.

‌

Thank you in advance
