hi all,
i am trying to correlate a behavioural measure with the contrast of a
task ant rest condition on a voxel by voxel basis in a patient group
using a simple regression under basic models (spm2). the design is
created succesfully, but when i estimate the design an error occurs.
first the parameters are estimated correctly, but when estimating
spatial non_sphericity spm returns:
> Spatial non-sphericity (over scans) : ...estimating derivatives
> Spatial non-sphericity (over scans) : ...writing resels/voxel image
> ??? Second argument must be numeric, real, full and double.
>
> Error in ==> C:\MATLAB6p5\caspers_scripts\spm2\spm_resels_vol.dll
> Error in ==> C:\MATLAB6p5\caspers_scripts\spm2\spm_spm.m
> On line 880 ==> R = spm_resels_vol(VM,FWHM)';
>
> ??? Error while evaluating uicontrol Callback.
does anyone know what the problem is?
cheers,
casper
