Hi, I don't think you can change this in design.fsf (though we may add that in future). Currently to change this you would need to edit $FSLDIR/tcl/ featlib.tcl and find the relevant call to "flirt" - it's the line: fsl:exec "${FSLDIR}/bin/flirt -ref $ref -in $in -out $out - omat ${out}.mat -cost corratio -dof $dof -searchrx -$search $search - searchry -$search $search -searchrz -$search $search -interp $interp $init $in_weighting" Cheers.
