Hi Sabrina,

Consider an independent analysis using afni_proc.py,
which might make your life much eaiser.

As it stands, you might be comparing +orig space with
+tlrc space data, though it is hard to say without
actually seeing any commands. You seem to resample
the data via the afni GUI, but it is not clear what
space that is in (orig->orig or ->tlrc).

In any case, that might be more clear if done on the
command line. If possible, do not actually use any
GUI for data processing. It becomes an unknown and
hard to describe step, as we are seeing.


Would you please provide the output of:

3dinfo Lag4_AllCoefficients+tlrc | head -n 30
3dinfo Lag4_AllCoefficients+tlrc | tail -n 30

Or, you could email me the entire 3dinfo output:

3dinfo Lag4_AllCoefficients+tlrc


Exactly what are you doing to see that WARNING
message? Is there a command? Is it from the afni
GUI? Would you please be precise about that?
