-input DSET [DSET …] [-help] (-TR_match | -add_TR | -add_slice_times | -copy PREFIX [PREFIX …])

Overview

This program does various things with BIDS formatted datasets created
with dcm2niix_afni or dcm2niix.  The main point as of now is to pull
information from the matching json file and 3drefit the input dataset.
If you just want info from the matching json file, use abids_json_info.py.

Caveats

This assumes that the nifti dataset was converted from dicoms using
dcm2niix_afni or dcm2niix with the -b (BIDS) option. So a json file and
matching dataset in NIFTI format should be present. (NO AFNI FORMAT...)

The json file should end in .json (lower case) as outputted from dcm2niix.
The program will try to find a json file that matches the prefix of the
input dataset.
Like this:
     my_bids_fmri.nii.gz <-> my_bids_fmri.json

For most options, 3drefit will be run on the -input dataset(s).
So the dataset(s) will be overwritten!!
Make sure you want to do this!!
All of the caveates for 3drefit apply here...!!
(https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/programs/3drefit_sphx.html)

For example, when using -add_TR, if the dataset has slice time offsets,
these will be scaled by the factor newTR/oldTR. So you may want to
use -add_TR BEFORE -add_slice_times. However, afni_dcm2niix usually
adds the correct TR to the dataset header automatically. So you
should not need -add_TR...

Also, this has only been tested with 3d+time fMRI data acquired in the
axial (z or k) direction. If you have problems with data acquired in the
sagittal or coronal direction, post to the message board.

Example

abids_tool.py -add_slice_times -input my_bids_fmri.nii.gz

Options

Required arguments:
  -input DSET [DSET ...]
                        At least one 3d+time dataset.

Only one of these:
  -TR_match             Check if the TR in the json file matches the TR from
                        input dataset header. (1 if match)
  -add_TR               Add the TR from the BIDS json file to the input
                        dataset using 3drefit.
  -add_slice_times      Add the slice times from the BIDS json file to the
                        input dataset using 3drefit.
  -copy PREFIX [PREFIX ...]
                        Copy both the NIFTI dataset(s) AND matching .json
                        file(s) to PREFIX. Must have the same number of
                        prefixes as datasets!

Optional arguments:
  -help                 Show this help and exit.
