Regexp error for first level analysis after changing FWHM

[Lisa Rosenblum]

Hi all,

after prerpocessing fMRI Data with a smoothing kernel of [8 8 8], I tried running a first level analysis, defining conjunctions. I got the following error (see below). But - my first level script ran without any problems when I have used a smoothing kernel of [6 6 6] for preprocessing.  Is the "regexp" error related to the change in smoothing kernel?

This issue is caused by the conflict between SPM function and Matlab functions.  You can start SPM by typing spm in matlab console first and run the scripts. This will allow matlab to call the function from SPM.  Alternatively, adding path to the SPM subfolders can solve this problem. But this does not always work.
