# brkraw-mrs

A BrkRaw converter hook that adds single-voxel MRS support to the BrkRaw ecosystem.
This package ports the Bruker MRS workflow from spec2nii and exposes it as a
first-party BrkRaw hook.

## What it does

- Detects single-voxel MRS scans (PRESS, STEAM, SLASER) from ParaVision metadata
- Reads spectroscopy data from `fid` or `rawdata.job0`
- Converts data to NIfTI-MRS (NIfTI-2 preferred) with JSON header extensions

The goal is to make single-voxel MRS data usable within standard MRI analysis
workflows supported by BrkRaw.

## Install (BrkRaw Hook Standard)

Install the package and register the hook with BrkRaw:

```bash
pip install brkraw-mrs
brkraw hook install brkraw-mrs
```

To install by entrypoint name:

```bash
brkraw hook install mrs
```

To view the hook documentation:

```bash
brkraw hook docs brkraw-mrs --render
```

## BrkRaw Usage

```bash
brkraw convert \
  /path/to/bruker/PV_dataset \
  --output /path/to/output \
  --sidecar
```

## Support

Tested with Bruker ParaVision standard datasets:

- PV360 3.5-3.7 (PRESS)
- Other MRS sequences and older ParaVision versions are untested

Notes:
Data ordering for PRESS SVS is assumed as:

```plane
(1, 1, 1, n_points, n_averages?, n_dynamics?, n_coils?)
```

If a dimension is missing or equals 1, it is omitted.

## Contributing

This repository provides a foundational implementation of single-voxel MRS
support within the BrkRaw framework. Contributions from MRS researchers are
encouraged to help validate, refine, and extend the workflow across sequences,
acquisition schemes, and ParaVision versions.

This hook is a port of the spec2nii Bruker MRS workflow. See `NOTICE` for
