-
1. Make a folder with text
parameter files.
-
a. Open a new folder.
-
b. Select this folder
as the write directory.
-
c. Make a koch window.
Set its parameters, other than a and D, with
the 'Init!' and 'Step!' buttons.
-
d. 'Series
/ make parameter files' command. Select function, input the parameters.
-
2. Generate the corresponding
TIF image files.
-
'folder /
make images'
-
(Hold down the control
key for more instructions).
-
3. Make the marks file:
'folder / marks file'.
-
(Hold down the control
key for more instructions).
-
The marks file can
plot the a, D locations on the Koch family chart:
'Mark / restore' , select the file.
Sample marks file
( Text, tab delimited.)
a d category image
0.0 1.0 8 c00
0.01237 1.0175171 8 c01
0.02475 1.0349731 8 c02
Category - if one of ("R"
"G" "B" "M" "C" "Y"), will
make a dot of the appropriate color. Otherwise,
will print the category in position as text.
Later, merge the marks
file with the stats file (see below) to add the
image names and a and D values used to generate the fractals,to
the spreadsheet (in the stats file) which has the measured values
for various step length ranges.
-
4. Make the blob files -
outlines of the fractals in the image files.
-
a. 'TOOLS / blob'
makes the blob button window.
-
Set the statistics:
'stats / set stats', select area and the boundary
fractal statstics.
-
b. 'TOOLS / process
folder' makes process folder button window.
-
c. '*process folder*
/ files in folder / blob'
-
Set threshold values
to 1 1.
-
c. '*process folder*
/ blob stats to file
-
This is the spreadsheet
to merge with the marks file.
-
5. Merge the spreadsheet
with the marks file:
-
a. 'TOOLS / spreadsheet'
makes the spreadsheet button window.
-
b. '*spreadsheet*
/ Spreadsheet / merge
-
1. Select the
marks file.
-
2. Select the
spreadsheet file from step 4, <date>-stats.txt
-
3. Select the
image collumn for the marks file.
-
4. Select the
blob file collumn for the spreadsheet file.
-
6. Import the <date>-mrg.txt
file from step 5 into Excel.
