Dear AFNI experts,

I am a beginner user of AFNI.

I am trying to aligns my anatomical dataset to a "master" dataset by using following command:
$ 3dTagalign -prefix ./ortho -master /usr/local/share/brainhull/master+orig anat+orig

But it fails and throws out an err msg:
++ RMS distance between tags before = 132.68 mm
** Invalid transform matrix computed: tags dependent?
** computed [matrix] and [vector] follow:
[ -0.06436 0.35361 0.93318 ] [ 2.20667 ]
[ 0.02433 0.93539 -0.35277 ] [ 1.07087 ]
[ 0.99763 -0.00000 0.06880 ] [ -2.33825 ]

Could anyone please give me some hints that what could went wrong with my dataset? Thank you in advance!
