Dear Jesús,
You can also have a look at the Neuromorphometrics atlas that comes with
SPM:
VM = spm_atlas('mask','neuromorphometrics','3rd Ventricle');
VM.fname='3rd_ventricle.nii';
VM = spm_write_vol(VM,VM.dat);
spm_image('display',VM.fname);
Best regards,
Guillaume.

It would be very helpful when creating a ROI located next to the ventricles and therefore some voxels could fall in these areas. The problem would be solved subtructing the ventricle ROI to the target ROI, but I don't know from where I can take a well-defined ROI for the ventricles. I know the "TD Labels" map from the WFU PickAtlas, but the maks for the ventricles aren't very accurate...
