Compensation Digitization Errors
Contents
Sometimes compensation will introduce a digitization error as seen in the red box in the figure below. The digitization error of the FL1-H (+) population in the lower right-hand quadrant after compensation (figure T8.30) can easily be corrected by adding a range of random values. Digitization errors and adding a range of random values is further discussed in Editing a Compensation Definition topic. Please follow the steps below to learn how to correct for digitization errors.
Figure T8.30 - Digitization errors can be seen highlighted in the red box.
| 1. | Select File tab→Open Layout. |
| 2. | Open the layout ManualComp.fey found in the Tutorial Sample Data archive. |
| 3. | Click on the Digitization Errors page tab. |
Notice the digitization error of the FL1-H (+) population in the lower right-hand quadrant after compensation. To correct for the digitization error:
| 4. | Select the Data→Data Info→Compensations command |
| 5. | Select the Create Manually folder→DigitizationError compensation definition (figure T8.31) |
Figure T8.31 - Selecting the DigitizationError compensation definition for editing.
| 6. | Select the Create Manually folder→DigitizationError compensation definition (figure T8.31). |
| 7. | Type 2.0 in the Range of random value to add when converting log data field (indicated by red box in Figure T8.32). |
The plot will update in real time to reflect the change and the FITC(+) population in the lower right quadrant will now appear without the digitization error. The random value entered above was added to visually correct the data displayed in the 2D plot.
