Dear Rita,

that's right. If you want to create a NIfTI mask image from a VOI.mat file, you can try the following:

load SPM.mat

load VOI_xxx.mat

XYZ = round(SPM.xVol.iM*[xY.XYZmm;ones(1,size(xY.XYZmm,2))]);

spm_write_filtered(1,XYZ,SPM.xVol.DIM,SPM.xVol.M,'','img_VOI_xxx.nii');

Best regards,

Guillaume.

Hi,

Am I correct that a nifti image of VOIs is not created if one uses the GUI, but is created if one uses the batch module?  If so, is there a pretty easy way to create the niftis in the GUI or in matlab?
Thanks!

Rita
