This application allows you to view the data values from an image file as a table of numbers.
Select a file or enter an image window number in the File field. When the file loads, the area at the bottom of the dialog will be filled with a table of numbers corresponding to the data values in a region of the file. Along the bottom of this table are the x coordinates (numbered from zero) and along the right are the y coordinates (also numbered from zero). The data values shown in the table have been scaled; multiply by the scale factor shown in the second line of the dialog to get the approximate data value (it's approximate because after scaling the value has also been rounded to the nearest integer). Other fields at the top of the dialog will be updated with the dimensions of the file and some of some statistics of the region shown.
To change the portion viewed in the table, use the scroll bars next to the table to change the x and y positions. Adjust the z section or time point shown using the sliders just above the table. Change the wave shown by selecting one the wave toggles. If you're working with data from an image window, the region shown in the table will be outlined in red. You can move this region by clicking elsewhere in the image with the left mouse button or by clicking in the red rectangle with the mouse button and dragging it. Changing the section shown in the image window will cause the table of values in the Examine Data dialog to be automatically updated.

These are the dimensions of the full dataset. The numbers, in the order shown, are the number of points in x (number of columns), number of points in y (number of rows), number of sections in z, number of wavelengths, and number of time points.

Multiply the values shown in the table by the value shown to obtain the original data values (out to the precision that has been specified). The scale factor is always chosen to be a power of ten and can vary as you move around in the file.

A handful of statistics are calculated for the region in the table. These are the minimum and its x and y coordinates, the maximum and its x and y coordinates, and the mean.
When viewing complex data, the minimum and maximum reported are the data values with the minimum and maximum amplitude. When viewing floating point data (real or complex), any not-a-numbers or infinities are not included in the calculation of the minimum and maximum, but are factored into the calculation of the mean.

This set of toggle buttons indicates the wave currently being shown (when the wavelength is a meaningful value, it will be shown next to the toggle). Selecting a different toggle will cause that wave to be displayed.

Use this slider to change the z section currently in view. The number of the current z section (zero is the first one in the file) is shown above the slider.

Use this slider to change the time point currently in view. The number of the current time point (zero is the first one in the file) is shown above the slider.
