T-RunProj

Overview

T-RunProj combines (either as a sum, average, or maximum value) intensity information from multiple time points in the input data set. The controls for selecting and processing a region are the same as in many other application. There are additional controls to set the number of sequential time points combined, the number of time points stepped from the beginning of one group of time points to combine to the next, and how the intensity information is combined.

Step size

Use this text field to set how many time points to move ahead from the first time point in one group whose intensities are combined to the first time point in the next group. For instance, if you selected a step size of 4, regardless of how many time points are grouped, the groups would start at tstart, tstart+4, tstart+8, .... tstart is the starting time point from the T field.

Group size

Use this text field to set how many time points are combined for the result in one output time point. For example, if the number of time points combined is three, then the time points tstart, tstart+1, and tstart+2 are combined to form the first time point in the output. tstart is the starting time point from the T field. If the step size was also three, then the time points tstart+3, tstart+4, and tstart+5 would be combined to create the second time point in the output. If the step size was two, than the second time point in the output would be a combination of the time points tstart+2, tstart+3, and tstart+4.

Method

Use the menu next to the "Method" button to select how time points are combined:

Sum
Simply adds the intensities from the different time points to determine the output value. If the output file uses integers for the pixel values (this is set with the Mode menu and defaults to be the same format as the input file), the result can overflow giving strange looking output.
Average
Performs an unweighted average of the different time points to determine the output value.
Max
The output value is set to the maximum intensity from the different time points.
