Batch Command Line Processing Tutorial

In this tutorial we will learn how to run sift on the command line, loading a library, running queries then running PCA and using that for outlier detection. once we run through the commands step by step we will use them to create a batch script that can be used to execute them automatically, we will include so logic to automate the process even further.

Running on Command Line

First we need to run Sift on the command line, on your keyboard press the Windows Key + R in the run window type in cmd and press enter, this will open a command line terminal.
Then change the directory to Sift's install location
Next to launch sift we need to call the .exe and pass the argument –NoGUI
This will open another console that we can use to interact with Sift
In the new console we will load a library, enter the command –LoadLib directory “Path to downloaded library”
Next load and run a predefined query by entering the command –LoadQuery file “Path to query definition file”
Select all signals by running –SelectSignals (Ensure all signal groups and work-spaces have been selected)
Run a PCA with the name “Outlier_PCA” –RunPCA name “Outlier_PCA”
Now we will run our first round of outlier detection run an Local Outlier Factor test with the command –RunLOF grouping “group” autoExclude This will find any group level outliers and exclude them automatically
Now lets export the results of this LOF test run the command: –ExportPCA file “Path to exported txt file” exportFormat “transposed” LOF LOFThrehsold
Next we will run another LOF test, this time on workspaces: –RunLOF grouping “workspace” autoExclude
Now export the results of this LOF test as well: –ExportPCA file “Path to exported txt file” exportFormat “transposed” LOF LOFThreshold
Finally, lets save the project so we can view it in the GUI if needed: –SaveProject file “Path to saved project”
