Hi Turk,
Did you move the data after having run the first-level analyses? The SPM.mat file contains full path information to the functional volumes & any other inputs, so if you move these data, then SPM cannot find the images based on the path information. You can either:
1. Put the data back to the original location
2. use spm_changepath to change the old path information to the new.

Subject: [SPM] VOI Error
Hi SPM users,
I am using spm5 to extract the timecourse through the VOI but I get the following error:
??? Error using ==> spm_sample_vol
Cant open image file.
Error in ==> spm_get_data at 41
Y(i,:) = spm_sample_vol(V(i),XYZ(1,:),XYZ(2,:),XYZ(3,:),0);
Error in ==> spm_regions at 182
y = spm_get_data(SPM.xY.VY,xSPM.XYZ(:,Q));
??? Error using ==> waitfor
Error while evaluating uicontrol Callback
??? Error using ==> spm_input at 1466
Input object cleared whilst waiting for response: Bailing out!
Error in ==> spm_VOI at 77
SPACE = spm_input('Search volume...',-1,'m',...
??? Error while evaluating uicontrol Callback
Any suggestion ar advice would be grealty appreciated.
Thanks in advance
