#### Procedure
1. This step can be omitted. Process a WT data with Fluctuation Analyzer (FA) to obtain WT.res (only loading data and saving data steps are needed). In FCSPipeline KNIME workflow, fill a WT user input and execute Python Source node. Use returned offset value for correction steps in further FA sessions for FP and POI.

2. Perform two separate sessions of FA analysis: for FP and for POI. Do all intermediate FA steps (correlations calculation, correction, fitting of correlations with ACF) to obtain mFP.res and POI.res. **Important:** do not forget to save fluctuation traces with ACF fitting curves (Export all traces button) as .cof, .itr files.
3. Prepare the following [structure of files](structure of files).
4. Specify parameters in a main user input
> You can change any parameters or leave default values. The explanation of every parameter can be founded in a description menu of KNIME node.
