This section describes the purpose of each function in the tool and the associated parameters.
Basic data interaction is provided at the top of the tool.
measure allows the size of regions within the image to be measured. line allows a line to be drawn, returning its length. region allows a polygonal region to be defined, returning its area. mask calculates the area of the binary mask image. The units of these measures are either mm or pixels depending on whether image scale information is available. (Currently mm are only available for NEMA image types).
The plot functions produce graphical information from pixel locations. flow/T produces a flow-time graph at the pixel location, conc/T produces a concentration-time graph for the pixel and gamma fit fits a Gamma variant to the data. More detailed explanations of these functions are given in below. For each of these functions an image calculator graph tool must be available and dynamic timing information must have been loaded.
The next row of buttons stim params, gamma_params and perm params provides dialog boxes for the subsequent analyses.
