I always find those problems when i begin to matlab...and then the following problem occurs in CONN toolbox. is this linked??? The error occurs when trying to use slice time viewer with MNI bounderies...
Please help, I will be very thankfull!!!!
kind regards

"Moving the toolbox files to a private folder that is only added to path when needed (and then removed from path) is good idea."
That is not what I suggested.
Private folders cannot be explicitly added to the MATLAB Search Path, nor can they be expliclty removed. Nor is there any point in adding or removing a private folder from the Search Path anyway, as their scope is automatically limited (which, as I wrote earlier, is the point of using them).
Attempting to add a private folder to the MATLAB Search Path gives this warning:
and the private folder is NOT added to the Search Path (nor can it be).
I recommend reading the link I gave to understand what private folders do:

People I love you. In the end I set the Path to default and added the toolboxes again. Now all my problems are gone. So I guess the one who used my computer before added some folders of SPM which shouldn't be added. The "mother"-folder is enough. And now my second toolbox CONN is working well, so the errors were bound together.
Thanks for the help!!!!

None of the toolboxes are crashing - those are just warnings that you've got two functions with the same name.
Don't delete all toolboxes! You just need to find the one that's causing problems and move it to a different directory that isn't on your matlab path. Keep it - someone might need it.
To find the directory of the functions that have bad names, by using which():
which iscolumn -all
That will return a list of files that have that name including Matlab's files. Do that for several of the functions listed in the warnings and hopefully you'll see a pattern of where they are stored and which toolbox that are associated with (if any). Make sure you're not messing with Matlab's files, though. Don't move them and certainly don't delete them. Only change the unwanted files. You can moved them to a new directory.

as you can see here spm seems to be involved. probably one of the most used toolboxes in the world`?? :-D
I am mainly trying to figure this out because i have some small problems with the CONN toolbox which can stand alone but originally is a sub toolbox of spm...
so i guess i will try to delete and reinstall spm and conn and see if i am happy then??

The spm12 thing is definitely the culprit. Don't delete anything. Just move the custom files that are causing problems so they are no longer on Matlab path, restart matlab, and see if the problem goes away. But you probably shouldn't delete those files ever since others may need them at some point.
