my application contain 17 factors substituted accordingly in the sc1gr files, with a regression results of average 75 for all class types, with a demand extrapolated for these covers until 2050,
I am finding difficulty in understanding my outcomes, as the probability maps of a class is showing the same value for all the grids in all the years.

Answer by Akash Shah

The constant value in the probability files could indicate an issue with the calculations or data inputs. It is difficult to determine the exact cause without more information. You may need to review your input data, regression results, and demand extrapolation to identify any errors or inconsistencies. Additionally, it might be worth checking if there are any specific settings or parameters in the Dyna-CLUE program that could be affecting the probability calculations.

Hello,


I am getting the error "Same land cover cannot change autonomously in two different new land covers" after pressing the button RUN, I have checked all my files and don't understand where it could come from, do you have an idea to help me?


Thanks!

Answer by Robert Polubinski

Based on available data posted on the Internet, it appears that the program is in the files that you have. You have to check them to make sure that the rows and columns have the same number as the land uses. According to a user, if you have for example 115, it indicates that autonomous change is after 15 years. Now, open the file and check what I have said.


You can also check the official support forum where the users and developers are talking about Dyna-CLUE.

I have a problem with Dyna-Clue model calculations - it interrupts and in log.fil file appears the information: "Too many constraints defined". Did anyone encountered a similar problem?

Answer by Robert Polubinski

I have used all the available resources to look for this issue, but there isn't anything available. No user guide, troubleshooting page, document, etc.


However, I see that the CLUE version is available in full mode from the IVM website (the website is recommended by the original developers).

Replace the installed version and then repeat the process. Additionally, go to Help > About and note the developer's contact email addresses or phones and contact them regarding this issue.

My computer is running on 64bit OS. I can not install Dyna-CLUE because it says "The version of this file is not compatible with the version you are running". I would appreciate any help. Thanks!

Answer by Julia Bocchetta

Dyna-Clue is a 32bit compatible application. It wasn't designed to run in a 64bit environment, but you could try using the compatibility mode. If it still doesn't work, you might need to install Windows XP through VirtualBox in order to make it work.

I have a problem when using convert.exe, I can't run it. It shows "Access violation at module BORLNDMM.DLL" something like that. I use Windows 7 32bit and set compatibility to Windows XP SP2. What should I do?

Answer by Stephen Prastman

If you encountered that error, it means the software is trying to access a part of the memory that's already in use by another application or file. Try closing down all the applications and then disable them from boot using Start > Run > msconfig. Switch to Startup and disable all the apps, reboot the PC and then start the software. If you still encounter issues, then it's possible there is a problem with compatibility and you need to obtain a version that was created especially for Windows 7.

I'm working with CLUE-S to model the South Nation reservation area in Ontario, Canada. I inputted all files needed in CLUE and once I pushed the Run button I received an error.

Answer by Pete Clapp

You're receiving the error, because your files are not configured correctly or they are corrupted. In order to fix the problem, remove the software from your computer, reboot the PC, install the application again and use the user guide provided by the developer to model the framework. If you still have issues, I suggest you contact the support team using the information from the official web page.

I need to add -9999 as values for NODATA. I've tried to do that by reclassifying the raster, but it haven't got a result. Are there any other methods?

J
Answer by Julia Bocchetta

There is a tutorial available from the VU University Amsterdam. The PDF file uses Dyna-CLUE and informs you how to add values to the NODATA tree. I recommend checking the PDF using the following website. Use Adobe Reader to open the File. To fastly identify the required information, press CTRL + F, then type nodata and read the explanation.
