This patch works for me: ```patch diff --git a/bob/bio/base/script/verify.py b/bob/bio/base/script/verify.py index f26bf69..c8857c2 100644 --- a/bob/bio/base/script/verify.py +++ b/bob/bio/base/script/verify.py @@ -259,7 +259,7 @@ def execute(args): tools.preprocess( args.preprocessor, groups = tools.groups(args), - indices = tools.indices(fs.original_data_list(groups=tools.groups(args)), None if args.grid is None else args.grid.number_of_preprocessing_jobs), + indices = tools.indices(fs.original_data_list_files(groups=tools.groups(args)), None if args.grid is None else args.grid.number_of_preprocessing_jobs), allow_missing_files = args.allow_missing_files, force = args.force) ```
