Creating a Data Preprocessor Instance
Use a Data Preprocessor instance to harmonize measurement data from different sources and make it easier to compare in a report. In DIAdem you define how the data is harmonized and save the procedure in a DPP file you upload to the Data Preprocessor instance.
Note If you want to use a Microsoft SQL Server
database, enable the setting before creating a Data Preprocessor instance.
- In Data Preparation, click Data Preprocessor Instances.
-
Click
New » Data Preprocessor Instance to start the configuration wizard.
- Enter a name and click Next.
-
Configure the data areas. The Data Preprocessor instance takes the data from the raw data area, transforms the data into a consistent form, and stores the data in the processed data area. Use a UNC path to specify the folder. An example UNC path is
\\Server\MyFolder.
Parameter Description Example Name Name of the data areas. MyRawAndProcessedData Raw data Folder containing the raw data. \\MyServer\Data\Raw_Data Processed data Folder where the Data Preprocessor instance saves the harmonized data. \\MyServer\Data\Processed_Data - If you are using a Microsoft SQL Server database, enable MS SQL support and specify the settings for the database connection.
-
Specify the configuration mode.
Option Description Use default configuration Converts the raw data to TDM and calculates the minimum and maximum values. Use custom configuration Harmonizes the raw data according to the data preparation procedure (*.dpp) you upload. -
Select the instance you created and click
» Start to start the instance.
