Usage: 3dAutobox [options] DATASET
Computes size of a box that fits around the volume.
Also can be used to crop the volume to that box.
OPTIONS:
--------
-prefix PREFIX = Crop the input dataset to the size of the box, and
write an output dataset with PREFIX for the name.
* If -prefix is not used, no new volume is written out,
just the (x,y,z) extents of the voxels to be kept.
-input DATASET = An alternate way to specify the input dataset.
The default method is to pass DATASET as
the last parameter on the command line.
-noclust = Don't do any clustering to find box. Any non-zero
voxel will be preserved in the cropped volume.
The default method uses some clustering to find the
cropping box, and will clip off small isolated blobs.
-extent: Write to standard out the spatial extent of the box
-extent_ijk = Write out the 6 auto bbox ijk slice numbers to
screen:
imin imax jmin jmax kmin kmax
Note that resampling would affect the ijk vals (but
not necessarily the xyz ones).
Also note that this value is calculated before
any '-npad ...' option, so it would ignore that.
-extent_ijk_to_file FF = Write out the 6 auto bbox ijk slice numbers to
a simple-formatted text file FF (single row file):
imin imax jmin jmax kmin kmax
(same notes as above apply).
-extent_ijk_midslice = Write out the 3 ijk midslices of the autobox to
the screen:
imid jmid kmid
These are obtained via: (imin + imax)/2, etc.
-extent_xyz_midslice = Write out the 3 xyz midslices of the autobox to
the screen:
xmid ymid zmid
These are obtained via: (xmin + xmax)/2, etc.
These follow the same meaning as '-extent'.
-npad NNN = Number of extra voxels to pad on each side of box,
since some troublesome people (that's you, LRF) want
this feature for no apparent reason.
* With this option, it is possible to get a dataset that
is actually bigger than the input.
* You can input a negative value for NNN, which will
crop the dataset even more than the automatic method.
