3.4    Selecting FRAP Model
After loading the FRAP image and setting up all the required ROIs, users can proceed to select possible models that may fit the data. VFrap 1.1 supports two types of models: diffusion dominant and reaction dominant. There are two available models of diffusion dominant type: diffusion with one or with two diffusing components. The only available model of reaction dominant type is the reaction off rate model. Users can choose one or more of these model types. The “Choose Model Type” wizard has only one page. To select the model users just need to check the checkbox related to the specific model type. Figure 3-9 shows the wizard.
