++ Authored by: B. Douglas Ward
Usage: from3d [options] -input fname -prefix rname
Purpose: Extract 2D image files from a 3D AFNI dataset.
Options:
-v Print out verbose information during the run.
- -nsize Adjust size of 2D data file to be NxN, by padding
- with zeros, where N is a power of 2.
- -raw Write images in ‘raw’ format (just the data bytes)
- N.B.: there will be no header information saying
- what the image dimensions are - you’ll have
to get that information from the x and y
axis information output by 3dinfo.
- -float Write images as floats, no matter what they are in
- the dataset itself.
- -zfirst num Set ‘num’ = number of first z slice to be extracted.
- (default = 1)
- -zlast num Set ‘num’ = number of last z slice to be extracted.
- (default = largest)
- -tfirst num Set ‘num’ = number of first time slice to be extracted.
- (default = 1)
- -tlast num Set ‘num’ = number of last time slice to be extracted.
- (default = largest)
- -input fname Read 3D dataset from file ‘fname’.
- ‘fname’ may include a sub-brick selector list.
-prefix rname Write 2D images using prefix ‘rname’.
(-input and -prefix are non-optional options: they)
(must be present or the program will not execute. )
- N.B.: * Image data is extracted directly from the dataset bricks.
If a brick has a floating point scaling factor, it will NOT
be applied.
- Images are extracted parallel to the xy-plane of the dataset
orientation (which can be determined by program 3dinfo).
This is the order in which the images were input to the
dataset originally, via to3d.
- If either of these conditions is unacceptable, you can also
try to use the Save:bkg function from an AFNI image window.
