Plot

Press Plot to plot two or three images (or volumes) against each other, mapping the result onto a 2-d plane.

Slice Plot

Press Slice Plot to plot three (or four) images (or volumes) against each other by adding the x, y, (z) plots over a specified z (or t) range into single slices.

3 2d Plots

Press 3-2d Plot to plot three images (or volumes) against each other by plotting each combination of two against each other. The three plots will appear in one image.

Exclude

Select Exclude to exclude the pixels from the X, Y, and Z images that sum to the range defined by 1 += e.

e Enter a value, in e, to indicate the width around 1 to use for determining the range.

Old-Style 3d

Press Old-Style 3d to select the fixed projection style of plotting for the 3-dimensional plot. For increasing values, the x axis is left to right, the y axis is bottom to top, and the z axis is lower-left to upper-right.

Note

The Rotate option is disabled if this is selected.

Scale

The zoom factor for enlarging or reducing the plot. By default these is calculated automatically to fit the entire plot into the plotting region. A value of 1 scales an axis to cover 0 to the absolute extreme for 3-dimensional plots and over the entire range for 2-dimensional plots.

	Enter a zoom factor, in Scale X, for the x-axis.
	Enter a zoom factor, in Scale Y, for the y-axis.
	Enter a zoom factor, in Scale Z, for the z-axis.
	Enter a zoom factor, in Scale T, for the t-axis.

Minimums ad Maximums

	Enter the minimum value, in Min X, to plot from the X image.
	Enter the maximum value, in Max X, to plot from the X image.
	Enter the minimum value, in Min Y, to plot from the Y image.
	Enter the maximum value, in Max Y, to plot from the Y image.
	Enter the minimum value, in Min Z, to plot from the Z image.
	Enter the maximum value, in Max Z, to plot from the Z image.

Rotate

Enter the amount of rotation (angle) for each axis. The plot will be rotated and the 2d projection will be displayed.

	Enter the rotation, in Rotate X, for the x axis.
	Enter the rotation, in Rotate Y, for the y axis.
	Enter the rotation, in Rotate Z, for the z axis.

Show Range on Plot

Press Show Range on Plot to create a rectangle (or box for 3d) region of interest on the plot image that correspond to the x pixel values, the y pixel values, (and the z pixel values for 3d) from the plotted images.

Roi Image

Press Roi Image to create a binary image from the original images, used to make the plot image, using the selected region of interest over the plot image. A pixel in the binary image is assigned to 1 if that pixel contributed to the region of interest over the plot image. If minimums and maximums are entered, only pixels from those ranges in the original images will be considered.

Note

For the 3-2d plot, the binary image will contain only points from the original images that plot to at least two of the three plots under the selected regions of interest.

Press Multiple Roi Image to create a multi-valued image from the original images, used to make the plot image, using the 4-connected clusters from the selected region of interest over the plot image. A single value is given to each cluster. Each pixel in the multi-valued image is assigned to a cluster if that pixel contributed to that cluster over the plot image. A contour map image of the clusters is created with the corresponding pixel values from the roi image.

Use Rectangles Select Use Rectangles to take the first and last point of the region of interest and create rectangles from those points to cover the whole image. Use these rectangles as the clusters for creating the multi-valued image.

Classification Image

Press Classification Image to create a classified image from the multiple roi image, where each pixel is assigned to one of the clusters by its Euclidean distance from the clusters' signatures over the original images used to make the plot image. If the image is not a multiple roi image, the current signatures are used.

	Output Select Binary to create a binary image for each cluster, 0 if pixel is not assigned to cluster, 1 if pixel is assigned to cluster. Select Theme Map to create one multi-valued image with the pixel value equal to the corresponding value of the cluster or the signatures order of appearance.
	Method Select No-Sigma to use the standard Euclidean distance classifier. Select Sigma to use the standard deviation version of the Euclidean distance classifier. Select MGDS to use the covariance matrix version of the Euclidean distance classifier. Select Angle to use the minimum angle classifier.
