¥Automatic creation of Òfollower datasetsÓ:
²After the anatomical +orig dataset in a directory is resampled to +acpc and +tlrc coordinates, all the other datasets in that directory will automatically get transformed datasets as well
åThese datasets are created automatically inside the interactive AFNI program, and are not written (saved) to disk (i.e., only header info exists at this point)
åHow followers are created (arrows show geometrical relationships):
Œanat+orig  ¨anat+acpc  ¨ anat+tlrc
å        ­        ø        ø
åfunc+orig   func+acpc   func+tlrc
åIn the class example, func_slim+orig will automatically be ÒwarpedÓ to our anat datasetÕs ac-pc (anat+acpc) & Talairach (anat+tlrc) coordinates
ØThe result will be func_slim+acpc.HEAD and func_slim+tlrc.HEAD, located internally in the AFNI program (i.e., you wonÕt see these files in the demo_tlrc/ directory)
¥To store these files in demo_tlrc/, they must be written to disk.  More on this laterÉ
