Hi Stam,
i executed bedpostx_datacheck on the bedpostx directory and the following is the log on the console

===================================
when i created bedpostx directory, i used whole brain binary mask
bedpostx <indir> [-n 2] [-w 1] [-b 1000]
but later when i run qboot, i used probability mask(Right_Accumbens) extracted from the standard H-O atlas
qboot -k data.nii.gz -m Right_Accumbens.nii.gz -r bvecs -b bvals
