Import Single Image Numeric Data

In this section, you will learn:

•How to import the data into FCS Express V5 to view 2D Plots and 1D plots.

 

This section pertains to data from a set of single images that were not obtained from a 96 well plate, such as images obtained from a slide.

After adjusting the export settings in CellProfiler and running your pipeline, you may proceed to analyze your images and import the data into FCS Express V5.

1.Load the Section4pipelineCOMPLETED.cp pipeline in CellProfiler.
2.Select the default input and output folders in CellProfiler to load and store the data.
3.Analyze the images in CellProfiler.

 

Importing the Single Image Experiment to FCS Express

Note on FCS Express Preferences before starting these steps of the tutorial:

The File selection dialog must be enabled:

A.Open the FCS Express User Options by choosing File→Options.
B.Flag the "When creating a new plot, always display the selection dialog" box in the Files/Directories category.

(Enabling this feature is not a requirement of FCS Express, it has been selected for convenience in this tutorial)

 

4.Open FCS Express V5.
5.Open the FCS Express User Options by choosing File→Options
6.Select Cell Profiler Options from the Data Loading category (Figure T24.35).
7. Select csv from the delimiter drop-down list.
8. Uncheck the Load path names from Cell Profiler table of contents file check box.
9.  Click OK to close the FCS Express User Options dialog.

 

Note: In this example there are no images associated with the data so the Load Images check box must remain unchecked.

The dialog should look like Figure T24.35 when you are done.

9.Select the Insert→2D Plots→Dot (Figure T24.36) command.

10. Click anywhere on the layout and the Select a Data File dialog will appear.
11. Browse to the Default Output Folder where you stored your output data from CellProfiler.
12. Change the Files of type: drop-down list to CellProfiler (*.cpout).  For this example, they will be labeled cells_05.cpout and nuclei_05.cpout (Figure T24.37).

13. Highlight cells_05.cpout.
14. Click Open.

Note: For this example we will use cells_05.cpout which will display data from the 5 minute time point objects classified in the IdentifySecondaryObjects module of CellProfiler which corresponds to the entire cell area. The file, nuclei_05.cpout, will display data from the 5 minute time point objects classified in the IdentifyPrimaryObjects module of CellProfiler which corresponds only to the nuclear area of the cells.

15. Select AreaShape_Area for the X-Axis parameter (Figure T24.38).
16. Select Intensity_MeanIntensity_Cytoplasm for the Y-Axis parameter (Figure T24.38).
17. Click OK.

A Dot Plot will now appear on your layout indicating that the data was successfully imported (Figure T24.39).

Note: you can easily change dot size by selecting Plot Options→Overlay within the Format ribbon bar.
