# compile-dcm2bids-config
Combine [`dcm2bids`](https://github.com/unfmontreal/Dcm2Bids) and [`d2b`](https://github.com/d2b-dev/d2b) config files into a single config file while preserving the integrity of each separate config file's various `IntendedFor` fields.

## Installation
For the basic functionality:
```bash
pip install compile-dcm2bids-config
```
If you have config files written in YAML you can install the `yaml` extra, for example:
```bash
pip install 'compile-dcm2bids-config[yaml]'
```
## Usage
```bash
$ compile-dcm2bids-config --help
usage: compile-dcm2bids-config [-h] [-o OUT_FILE] [-v] in_file [in_file ...]
Combine multiple dcm2bids config files into a single config file.
positional arguments:
in_file The JSON config files to combine
optional arguments:
-h, --help show this help message and exit
-o OUT_FILE, --out-file OUT_FILE
The file to write the combined config file to. If not specified
outputs are written to stdout.
-v, --version show program's version number and exit
```
## Getting Started
Suppose you have two config files:
**`example/config1.json`:**
```json
{
"descriptions": [
{
"dataType": "anat",
"modalityLabel": "SWI",
"criteria": {
"SeriesDescription": "*SWI*"
}
},
{
"dataType": "fmap",
"modalityLabel": "fmap",
"criteria": {
"SidecarFilename": "*echo-4*"
},
"IntendedFor": 0
}
]
}
```
**`example/config2.json`:**
```json
{
"descriptions": [
{
"dataType": "dwi",
"modalityLabel": "dwi",
"criteria": {
"SeriesDescription": "*DWI*"
}
},
{
"dataType": "anat",
"modalityLabel": "SWI",
"criteria": {
"SeriesDescription": "*SWI*"
}
},
{
"id": "my-func",
"dataType": "func",
"modalityLabel": "bold",
"customLabels": "task-rest",
"criteria": {
"SeriesDescription": "rs_fMRI"
},
"sidecarChanges": {
"SeriesDescription": "rsfMRI"
}
},
{
"dataType": "fmap",
"modalityLabel": "fmap",
"criteria": {
"SidecarFilename": "*echo-3*"
},
"IntendedFor": [0, "my-func"]
}
]
}
```
Then we can combine the two using the following command (outputs are written to stdout by default):
```bash
$ compile-dcm2bids-config example/config1.json example/config2.json
{
"descriptions": [
{
"dataType": "anat",
"modalityLabel": "SWI",
"criteria": {
"SeriesDescription": "*SWI*"
}
},
{
"dataType": "fmap",
"modalityLabel": "fmap",
"criteria": {
"SidecarFilename": "*echo-4*"
},
"IntendedFor": 0
},
{
"dataType": "dwi",
"modalityLabel": "dwi",
"criteria": {
"SeriesDescription": "*DWI*"
}
},
{
"dataType": "anat",
"modalityLabel": "SWI",
"criteria": {
"SeriesDescription": "*SWI*"
}
},
{
"id": "my-func",
"dataType": "func",
"modalityLabel": "bold",
"customLabels": "task-rest",
"criteria": {
"SeriesDescription": "rs_fMRI"
},
"sidecarChanges": {
"SeriesDescription": "rsfMRI"
}
},
{
"dataType": "fmap",
"modalityLabel": "fmap",
"criteria": {
"SidecarFilename": "*echo-3*"
},
"IntendedFor": [
2,
"my-func"
]
}
]
}
```
Notice that the `IntendedFor` fields have been updated appropriately.
## Python API
You can also use this tool from within python:
```python
import json
from pathlib import Path
from pprint import pp
from compile_dcm2bids_config import combine_config
config1 = json.loads(Path("example/config1.json").read_text())
config2 = json.loads(Path("example/config2.json").read_text())
all_together = combine_config([config1, config2])
pp(all_together)
```
The result being:
```python
{'descriptions': [{'dataType': 'anat',
'modalityLabel': 'SWI',
'criteria': {'SeriesDescription': '*SWI*'}},
{'dataType': 'fmap',
'modalityLabel': 'fmap',
'criteria': {'SidecarFilename': '*echo-4*'},
'IntendedFor': 0},
{'dataType': 'dwi',
'modalityLabel': 'dwi',
'criteria': {'SeriesDescription': '*DWI*'}},
{'dataType': 'anat',
'modalityLabel': 'SWI',
'criteria': {'SeriesDescription': '*SWI*'}},
{'id': 'my-func',
'dataType': 'func',
'modalityLabel': 'bold',
'customLabels': 'task-rest',
'criteria': {'SeriesDescription': 'rs_fMRI'},
'sidecarChanges': {'SeriesDescription': 'rsfMRI'}},
{'dataType': 'fmap',
'modalityLabel': 'fmap',
'criteria': {'SidecarFilename': '*echo-3*'},
'IntendedFor': [2, 'my-func']}]}
```
## YAML Configuration Files
This package can handle [`dcm2bids`](https://github.com/unfmontreal/Dcm2Bids) (or [`d2b`](https://github.com/d2b-dev/d2b)) configuration files written in YAML, the user just has to install the `PyYAML` package, either separately:
```bash
pip install pyyaml
```
or all at once via the installation "extra":
```bash
pip install 'compile-dcm2bids-config[yaml]'
```
If PyYAML is available, then configuration files ending with `.yml` or `.yaml` can be passed as input files:
```bash
compile-dcm2bids-config config1.json config2.yaml > combined.json
```
The combined configuration file can also be formatted as YAML by adding the `--to-yaml` flag:
```bash
compile-dcm2bids-config --to-yaml config1.json config2.yaml > combined.yaml
```
