+**Inputs**:
 
-	input_dir: str, directory of input csv files. This key is mandatory if input_type = "csv".
+- **input_info**: dict, input related information
 
-	input_folder: str, folder name of the input csv files, the specified folder contains the required input info for a specific extraction type like PDN, LSIO, HSIO etc. This key is mandatory if input_type = "csv".

-	op_run_name: \[optional\], str, the time stamp of the "Run" folder. It should be omitted or assigned empty string by default. Each time an extraction starts, a folder called "Run_(time stamp)" is created automatically. In order to hack into an existing Run folder, set the existing time stamp to this key.
