Usage: 3dAFNItoNIFTI [options] dataset
Reads an AFNI dataset, writes it out as a NIfTI-1.1 file.
NOTES:
* The nifti_tool program can be used to manipulate
the contents of a NIfTI-1.1 file.
* The input dataset can actually be in any input format
that AFNI can read directly (e.g., MINC-1).
* There is no 3dNIFTItoAFNI program, since AFNI programs
can directly read .nii files. If you wish to make such
a conversion anyway, one way to do so is like so:
3dcalc -a ppp.nii -prefix ppp -expr 'a'
OPTIONS:
-prefix ppp = Write the NIfTI-1.1 file as 'ppp.nii'.
Default: the dataset's prefix is used.
* You can use 'ppp.hdr' to output a 2-file
NIfTI-1.1 file pair 'ppp.hdr' & 'ppp.img'.
* If you want a compressed file, try
using a prefix like 'ppp.nii.gz'.
* Setting the Unix environment variable
AFNI_AUTOGZIP to YES will result in
all output .nii files being gzip-ed.
-verb = Be verbose = print progress messages.
Repeating this increases the verbosity
(maximum setting is 3 '-verb' options).
-float = Force the output dataset to be 32-bit
floats. This option should be used when
the input AFNI dataset has different
float scale factors for different sub-bricks,
an option that NIfTI-1.1 does not support.
The following options affect the contents of the AFNI extension
field that is written by default into the NIfTI-1.1 header:
-pure = Do NOT write an AFNI extension field into
the output file. Only use this option if
needed. You can also use the 'nifti_tool'
program to strip extensions from a file.
-denote = When writing the AFNI extension field, remove
text notes that might contain subject
identifying information.
-oldid = Give the new dataset the input dataset's
AFNI ID code.
-newid = Give the new dataset a new AFNI ID code, to
distinguish it from the input dataset.
**** N.B.: -newid is now the default action.
