Here is sub-NENAH004 image

Comes from here in preprocess.sh

if [ ! -f mask.mif.gz ]; then
    dwiextract -bzero $dwi.mif.gz - | mrmath -force -axis 3 - mean meanb0tmp.nii.gz
    bet meanb0tmp meanb0tmp_brain -m -F -R
    # Check result
    echo Check the results
    echo "mrview meanb0tmp.nii.gz -roi.load meanb0tmp_brain_mask.nii.gz -roi.opacity 0.5 -mode 2"
    mrconvert meanb0tmp_brain_mask.nii.gz mask.mif.gz
    rm meanb0tmp*
fi

We have now changed this by and testing different -f values for BET

The optimal BET-values are listed in QC_dwi.csv
