I'm trying to run a reaction-diffusion modeling program. Below is the link to the tarball. I was able to install it after editing the makefile (added -LX11R6 to the LIBS section, per generic instructions I found on a google search for the error message I got when make failed.) Here's the current problem: When I try to run the program with the sample parameters given in the readme.txt, I get the error message, "bad status from XAllocColorCells Segmentation fault" Note: I get occasional segmentation faults, possibly due to a flaky power supply. Those seem to be less frequent since I vacuumed the dust and cat hair out of the box. Here's a link to the tarball, in case anyone has the time or inclination to mess with it and/or offer advice. Oh yeah, I'm running SuSE 7.2. http://www.gvu.gatech.edu/people/faculty/greg.turk/reaction_diffusion/code/r... Thanks, Greg

Just a thought....if you bring up X with a different number of colors, does that effect the problem? I would advise trying them all (8, 16, 32) and see if the result is the same in each case. Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Thanks, Andy. I tried 8, 16 and 24. Can't seem to get 32 to stick. I think that's a limitation of my vid card if I remember correctly. Anyway, there was no difference. I get a quick flash like a window is opening, then it disappears and I get the error message. Greg
Here are a couple of things to check: - XAllocColorCells works with a PseudoColor visual. You may be running in TrueColor. Use xdpyinfo to find out. (grep for Color) - If you are in PseudoColor mode, you might not have enough free colors left. You might want to start a plain X session (no netscape etc) with a window manager like fvwm or twm. If you are familiar with vnc, you can start a vncserver in PseudoColor mode using the -cc 3 option. You may also want to modify xstartup (in your .vnc directory) to invoke a simpler xinitrc which starts fvwm or twm. -----Original Message----- From: wlug-admin@mail.wlug.org [mailto:wlug-admin@mail.wlug.org] On Behalf Of Gregory Avedissian Sent: Tuesday, March 04, 2003 11:43 AM To: wlug@mail.wlug.org Subject: [Wlug] reaction-diffusion program I'm trying to run a reaction-diffusion modeling program.

I'm running in TrueColor, and I'm already in fvwm2. Same thing in twm. I don't know anything about vnc, and I can't find anything about it on my computer (help, man or apropos). Can't find anything about PseudoColor, either. How do I switch it? Thanks. Greg Steve Freitag wrote:

Got it! I have to run two x servers at the same time (didn't know I could do that), the first one in TrueColor and the second in PseudoColor by starting the second one with startx -- :1 -bpp 8 and the program runs ok. This is cool. Now all I need to do is figure out what reaction-diffusion means. I saw the math for it, and um, it looks like Greek to me. Anybody know anything about patterns of animal coat spots/stripes? Can anyone here figure out the mathematics of acupuncture point locations? (I know, I'm in way over my head here.)

HI Greg, I'm glad to hear that you got it working!
and the program runs ok. This is cool. Now all I need to do is figure out what reaction-diffusion means.
Darn, I was almost impressed that you knew what reaction-diffusion meant. Now you went and burst my bubble. :-) If you want to see another cool program where the math will send you for a loop but it makes neat looking graphical figures, try surf. Also, rasmol is neat if you are into molecular modeling, or just looking a cool geeky looking pictures. :-) Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org
Andy, This program makes some pretty neat graphics, but it's very limited. I can choose the number of cells in x and y axes, and it makes spots or stripes. I have a qualitative understanding of it, but I don't know the math. A friend of mine said she'd look around for a book that explains it. Greg Andy Stewart wrote:
