For example, you can obtain the Median Fluorescence Intensity (MFI) of a population. (F) Temporal changes in gene expression profiles associated with glycolysis, tricarboxylic acid (TCA) cycle, and photosynthesis pathway during SCMV infection. Look at this compared to the result of a proper flat-field correction above. Much more robust statistic in that it is less influenced by skew or outliers C, Zandstra. Also create a Graphs view in flow Jo and then add the Median intensity. It will generate a pseudo-linescan "stack" with each slice representing the pseudo-linescan of a single-pixel wide line along the line of interest. Would segmentation be useful? My first query is that is the protocol listed above appropriate. Ultimately, like any piece of data, MFI should only be applied if you are absolutely certain that it is the best comparison to make, otherwise it is simply clutter on an otherwise clean histogram. To test this, we treated SCMV-infected maize plants once at 3 dpi with rotenone (5, 20, or 40M) to specifically inhibit the activity of mETC complex I.
