List files are a way to represent surface or image sequences. They are stored as ASCII format text files containing the filename of previously stored files on each line.
To create a list file, use the File | New menu command and select either image or surface list. An editor window will appear where file names may be typed in or added automatically using the File | Add File(s) menu option or the button. Individual files may be opened in a new window by double-clicking the file name in the editor.
Once a list file is created or opened, operations can be performed on the sequence. Available operations:
|Combine | Average||The average, or mean, of the population at each pixel location is calculated. Choose whether to propagate non-valid pixels to the average. If non-valid pixels are not propagated, aberrations to subtract are specified and overlay statistics can be generated.|
|Combine | Median||The median, (max + min )/2, of the population at each pixel location is calculated.|
|Combine | Modulation||The modulation image, , of the population at each pixel location is calculated.|
|Combine | Add and Subtract|
|Combine | Maximum and Minimum|
|Combine | Stitch||Choose the Zernike order or aberrations to remove. Overlay statistics can be generated for surfaces. As each data set is overlaid, pixel statistics are optionally gathered. See overlay statistics.|
|Analysis | Phase||Phase analysis is described here.|
|View | Animate||Display a movie of image frames or surface representation.|
