The 7500 software requires that the endogenous control be run on every plate within a study. If not, you will only see RQ values for the plate that contains the endogenous control on it. The other plates will have CT values for all the wells, but the software will not calculate RQ values. If you designed your experiments in this type of layout, you will want to do your analysis in the free DataAssist™ software instead. This program does not have the endogenous control requirement for every plate. Simply export the study results file from the 7500 software as a *.txt or *.csv file, and use that to create a new study in the DataAssist™ software. You should now be able to see RQ values for all samples, even those without an endogenous control on the same plate.
