This method by Fry (Tectonophysics, 1978) can be taken as
a statistical variant of the centre-to-centre technique introduced by J G
Ramsay (Folding and fracturing of rocks, McGraw,1967). While Ramsay's
method is ideally suited for . deformed aggregates with shared boundaries
(e.g. a colony of deformed corals), Fry's method (if the distribution of
aggregates is not Poissonian) can be used for aggregates of deformed
aggregates of any kind such as deformed quartz grains or pebbles. The
program developed very useful and versatile in the sense that complete
annotation of the plot and caption and legend and printing facility is
available in the very program and you do not, unlike other programs,
have to export the plot to other programs with graphic facilities. A is a
splash of the program and B the result of deformed pisolites from Germany.

Highlights: 1. The program has an image
window and a plotting window. 2. The image and the plot are zoomed
together. 3. The caption can be entered and edited for font and color. 3.
The legend can be edited in font and color. 4. At the click of a mouse,
the plot can be taken to print preview window and printed on the device in
LPT port. 5. The program has a HTML help file. .
