Marsbar Export

Hi All,

I'm having some issues exporting the ROI files.  I'm building the ROI off of an image file I made with ImCalc in
SPM, manipulating the file, then I want to export the ROI file back into an image format (or any other format
I can use in Matlab) as a cluster image.  However, when I try to export, I keep getting an error about the dim
(1, 4) (sorry can't quote the exact error because I'm on a different computer).

Any ideas on what's causing it/what I can do to fix it?

Thank you,
Shira

Re: Marsbar Export

An edit - Ok the exact error is: 
??? Error using ==> spm_create_vol5>create_vol at 32
"dim" field is the wrong size (1  4).

When the ROI is created in matlab is it changed to 3 dimensions and now it's
trying to export back out to 4?  How would I get around this?

Thanks,
Shira

Could you post the script that generates the error?

Thanks a lot,
