¥Step 3: Save your results:
H [Save] will write the current dataset values to disk
(overwriting any existing .BRIK file,
i.e., if you had edited this ROI earlier, the new changes would overwrite the old file)
åYou could also then choose another dataset to edit
H [Save As] will let you write the current dataset to disk under a
new name, creating a new dataset, then continue
editing the new dataset
H [Quit] exits editing and closes the plugin window, without
saving to disk any changes since the
last [Save]
åExiting AFNI has the same effect
H [Done] is equivalent to [Save] then [Quit]
¥Optional Drawing Steps:
H [Linear Fillin] lets you draw a 3D ROI not in every slice, but in every
third slice (say), and then go back and fill in the
gaps
åFor example, if you draw in coronal slices, then you
want to fill in the [A-P] direction (the default)
åIf you draw every nth slice, then you want to set the
Gap to n-1
åLine segments of voxels in the fillin direction that
have a current drawing value at each end, and
have no more than [Gap] zero voxels in between, will get their gap voxels filled with the drawing
value
íAfter you try this, you will probably have to touch up
the dataset manually
