FCS Express has been specially optimized for use with FCS Data files generated by Abbott's Cell-Dyn Sapphire® instrument. When the Sapphire software exports results from the instrument, it packages all of the separate cell populations into a single compound file. Most flow cytometry data analysis software cannot even open the compound file, but all you have to do in FCS Express is change a few settings to make Abbott files as easy as any other. See our poster from the 2005 ISLH XVIII meeting.
Below is an explanation of the different data sets in a typical Sapphire data file.
| Data Set Name | Explanation |
| WBCod | white blood cell optical data |
| RBCi | Red blood cell impedance data |
| PLTi | Platelet impedance data |
| PLTo | optical platelet data |
| HGBr | optical densisty readings for the hemoglobin measurement |
| HGBs | optical densisty readings for the hemoglobin measurement |
| CD3_4 | CD3/4 analysis |
| CD3_8 | CD 3/8 analysis |
| RETC | reticulocyte data |
| CD61 | CD61 (immunoplatelet analysis) |
