Usage: 3dRowFillin [options] dataset
Extracts 1D rows in the given direction from a 3D dataset,
searches for blank (zero) regions, and fills them in if
the blank region isn't too large and it is flanked by
the same value on either edge. For example:
input row = 0 1 2 0 0 2 3 0 3 0 0 4 0
output row = 0 1 2 2 2 2 3 3 3 0 0 4 0
OPTIONS:
-maxgap N = set the maximum length of a blank region that
will be filled in to 'N' [default=9].
-dir D = set the direction of fill to 'D', which can
be one of the following:
A-P, P-A, I-S, S-I, L-R, R-L, x, y, z,
XYZ.OR, XYZ.AND
The first 6 are anatomical directions;
x,y, and z, are reference to the dataset
internal axes.
XYZ.OR means do the fillin in x, followed by y,
followed by z directions.
XYZ.AND is like XYZ.OR but only accept voxels that
would have been filled in each of the three fill
calls.
Note that with XYZ* options, the fill value depends on
on the axis orientation. So you're better off sticking
to single valued dsets when using them.
See also -binary option below
-binary: Turn input dataset to 0 and 1 before filling in.
Output will also be a binary valued dataset.
-prefix P = set the prefix to 'P' for the output dataset.
N.B.: If the input dataset has more than one sub-brick,
only the first one will be processed.
* The intention of this program is to let you fill in slice gaps
made when drawing ROIs with the 'Draw Dataset' plugin. If you
draw every 5th coronal slice, say, then you could fill in using
3dRowFillin -maxgap 4 -dir A-P -prefix fredfill fred+orig
* This program is moderately obsolescent, since I later added
the 'Linear Fillin' controls to the 'Draw Dataset' plugin.
