This application takes an existing dataset and appends to it one or more low-resolution versions of the data. Each low-resolution data set is scaled down a factor of 2 in x and y from the previous set. The z-resolution of the low-resolution data can also be scaled down.
Enter the dataset to which you want to append low-resolution data in the first line. The next line will then display the x, y, and z sizes of the data. The following line will display the number of resolutions and z-scaling factor currently in effect for the data set. Enter the desired number of resolutions and z-scaling factor in the # of Resolutions and Z Scaling fields respectively. Then press the DoIt button to append the low resolution data.

The text field next to this button shows the number of resolutions to store. Allowed values are integers from 1 to n where 2^(n-1) is less than or equal to the number of pixels in x and y in the dataset.

The text field next to this button shows the number by which the low-resolutions sets are scaled down in their z resolution. Allowed values are integers from 1 to n where n^(# of resolutions - 1) is less than or equal to the number of z sections in the dataset.

This application can reduce the amount of low-resolution data that appears to be present in a file but can not decrease the actual size of the file. To trim the size of the file, use CopyRegion to copy the data to a new file (it only copies the highest resolution data) and then append the desired low-resolution data.
