Runerror with function work_on_collection in SGVFinder.py

[pangkun97]

When I used SGVF_cmd.py with paramaters: --min_samp_cutoff 1 --csv_output 'input_glob' 'output_dsgv' 'output_vsgv', it returned errors as follows:

The input files there were the output of ICRA_cmd.py and SGVF_PerFile_cmd.py with default parameters,
Could you help me fix this problem?
