some questions of running runCTRecon.py

[liu123-t]

Hi. I am running the code : python runCTRecon.py . some questions confused me.
for example, "prefixModelName": is it mean a path to store trained model?
and what is "prefixPredictedFN", can I change it?
what is "test_input_file_name" ?which kind image it store?

and I know"path_test indicates path for .nii.gz file", but how much datases path_test store? all the dataset or only
training set+validation set？
