Hi,

I have some 3D data converted to and from Analyze format. When I converted the
data back from Analyze to AFNI, the origin of the data was not set correctly,
so I tried to use

3drefit -orient LPI -duporigin originalData dataConvFromAnalyze

to put them in the same position, but 3dinfo showed that after 3drefit,
the two data sets are still not at the same position.
Anybody knows what was wrong? Thanks in advance.

George
