Hi!
I'm tring to compile and after ./configure I get this:
/root/.bashrc UNIX_BIN=/usr/local/bin SCR=/usr/local/grass5.0beta
GISBASE=/usr/local/grass5.0beta MACHINENAME=grass.lv.parnu.ee /bin/bash
scr/CMD/generic/CREATE_GMAKE.sh
/bin/bash: /root/.bashrc: Permission denied
make: *** [pre-install] Error 126
What's up?
Hanno

Subject: Re: Box Counting MethodI did something similar to study the sprectral response of
a high reolution sensor for each cell of a coarse resolution
sensor.I just made an script (I think that I actually contributed to Markus N.)
that produces a numbered image, i.e., like r.clump but each pixel has
an individual integer value.You could run a similar process for each given resolution and create a
suite of rasters (numbered.1, numbered.2, numbered.3 ...) that would
match as:numbered.1:
1 2 3 4 5 6 7 8 9
10 11 12 13 14 15 16 17 18
19 20 21 22 23 24 25 26 27
....numbered.2
1 1 2 2 3 3 4 4 5 5
1 1 2 2 3 3 4 4 5 5
6 6 7 7 8 8 9 9 10 10
....Then you select the resolution of your fracture maps
(0: no fracture; 1: fracture; if you have different types
of fractures, just add more categories) and use
r.stats with each numbered.x map and your fracture map,
to obtain, for each numbered.x, a file with 2 columns:numbered.1 fracture
1 0
2 0
3 1
4 1
5 6etc.
Export to your stats program and count the number of "1"
for each numbered.x. From this series you can calculate
the fractal dimension.It might seem complicated, but it's not.
