 #### Structure of workflow
--  two user inputs:
-   -  main user input
-   -  plot parameters input
+-  three user inputs:
+   -  main user input (general parameters)
+   -  plot parameters input (customizing your plot and setting the QC parameters)
+   -  WT user input (calculating the background offset for correction step in FA)
 -  loading metanodes:
-   -  collecting fluctuation data (FA WT, FA FP, FA dye metanodes)
-   -  collecting intensities (intensity data metanode)
--  data processing nodes (joiner, python scripts)
+   -  collecting fluctuation data (FP&POI, dye metanode)
+   -  loading images and coordinates (FP&POI&WT images metanode)
+-  data processing nodes (Python Script (2=>1), intensity calculation metanode )
 -  joiner metanode with Quality Check
--  visualization node and the final table

 #### Procedure 
-1.  Prepare the following [structure of files](structure of files)
-2.  Specify parameters in a main user input
+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 FA analysis including 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.

+5.  Fill a plot parameters input   
 > It will implement a Quality Check by filtering the points for calibration plot according to the bounders of statistics parameters specified by user.

-#### Interactive Visualisation of Calibration Plot
+#### Interactive Visualisation
 1.  Pick the point of interest in the calibration plot window to see fluctuation and correlation data from the respective FCS position.
 2.  Check the statistics parameters and level of bleaching at the headings of plots. 
 3.  Delete points that you consider have "bad" fluctuations or quality of fitting (list points to delete in plot parameter input).
