Thank you, pointflirt looks like it could be the perfect tool.
However, so far we are having trouble getting good results out of it. We
have tested pointflirt by creating matrix files using the voxels reported by
FSLview, and also by using the coordinates (in mm) as reported by FSLview.
We have even attempted to input scaled coordinates by subtracting the
coordinate values when the voxel values are at (0,0,0.) One obvious anomaly
is that the fourth column of the output matrix has a value that measures in
the 1000's.
1) Would you mind explaining scaled coordinates and their application as it
relates to this?
2) Might it have to do with plugging in both positive and negative values
when it can only take positive?
3) Are four points necessary to use pointflirt? Or can we just plug in 3
points, which is all we need to align in 3D space?
Sorry for all the questions, we're trying to hypothesize on why we're having
these issues.
Thanks again,
TS
