FCS Express: Statistics

In addition to the traditional statistics and tokens that FCS Express has always offered, FCS Express 6 offers several Statistical Functions, such as:

Below you see many of the statistics that are available for histograms and 2D plots.  These stats are arrayed in a Statistics window, which allows you to easily decide which stats to show within the displayed grid.

The following statistics are included in FCS Express 5 and FCS Express 6:


The Statistics window can be easily formatted to:

  • Add or remove columns
  • Rearrange columns
  • Change fonts
  • Change gates to display (for gate statistics)
  • Show calibrated or uncalibrated statistics for channel calibration
  • Show statistics in scientific notation
Gate Statistics window before formatting
Gate Statistics window after the following formatting changes:
  • Overlay # column removed and X Standard Deviation column added
  • font type and size
  • scatter gate no longer displayed
  • columns in the window are also being rearranged by dragging


Many different statistics are available, including percentiles, percent parent / grandparent, and robust CVs, as well as all of the basic statistics needed for data analysis. You can also have "percent positive" and sample concentration calculated directly on the statistics screen. All statistics can be copied to the clipboard for easy pasting into any Windows® program, or they can be added to your exports in a Batch Process of your entire dataset.


Below is another way to see statistics-- in a text box. Using our unique token features in combination with text boxes, you can build custom statistics tables that combine the information from multiple plots in your layouts. These can also include user-defined statistics or formulas, such as the ratio custom token shown in the bottom-right cell of the table. These text tables are an effective way of summarizing the results of an entire experiment.
