Introduction

**This software is no longer actively maintained. Please use Bruker's own ParaVision 360. You may also want to try BrkRaw which is actively maintained (though like all tools only tested an a small proportion of the Bruker files that have changed in undocumented ways over thee years).git **

This is a simple tool for converting Bruker ParaVision MRI data to the NIfTI file format. While every attempt has been made to provide robust support, the ParaVision format is inherently complicated, contradictory, poorly documented, and has included explicit errors. One is left wondering if this format is intentionally obfuscated. New versions have defined features and added new features that appear to conflict with existing older features. Therefore, it is often unclear what the correct solution is, and different tools (see links below) may provide different solutions. Users should use any Bruker conversion tools with extreme caution and encourage the vendor to directly support simpler formats (e.g. creating a NIfTI "hdr" header file when the Paravision files are generated could be done seamlessly and would greatly aid customers). As a professional company, Bruker has an obligation and incentive to help users access their data. Variations of this project have existed since 1999, and yet the situation has not improved. Any customer considering purchasing equipment or services from this company should demand they develop a cleaner, more transparent solution that will reduce costs in terms of support and potentially erroneous results.

This project includes both a drag-and-drop graphical interface (Bru2Nii) as well as a command line tool (Bru2). The compiled tools run on Windows, Linux and OSX without requiring any other files to be installed. The source code can be built using Lazarus without any other tools required. This project is inspired by the Perl script pvconv.

You can find pre-compiled binary executables with the latest release. Alternatively, one can recompile the latest version.

Usage (Command Line)

Provide the name of the Bruker format 'acqp' or 'subject' file you wish to convert. Here are a few examples for Windows

  • Convert all data from a subject Bru2 c:\mydata\subject
  • Convert single session Bru2 c:\mydata\10\acqp
  • Convert, appending protocol name to output filename Bru2 -p c:\mydata\10\acqp
  • Convert to specific folder Bru2 -o c:\output c:\mydata\10\acqp Here are examples for Unix
  • Convert all data from a subject Bru2 /Users/cr/dir/subject
  • Convert single session Bru2 /Users/cr/dir/acqp
  • Convert, appending protocol name to output filename Bru2 -p /Users/cr/dir/acqp
  • Convert to specific folder Bru2 -o /Users/cr/dir2/out /Users/cr/dir/acqp
Usage (Graphical Interface)

Drag and drop the Bruker 'acqp' or 'subject' file you wish to convert.

Installation

The easiest way to use this software is to download an executable compiled for your operating system. Versions are provided for Windows, MacOS and Linux. There are two programs: a command line version and a graphical interface.

Compile from Source
  1. You will want to install Lazarus. For Windows, download and run the unified installer. For Linux and OSX, you will want to install the lazarus, fpc and fpc-src packages.
  2. You can build these tools from the graphical interface. For example, launch Lazarus. Select Project/OpenProject and then choose project you wish to compile (for example Bru2Nii.lpr). Finally, choose the Run/Run command.
  3. To compile the console version from the command line, run either one of these commands "fpc Bru2.lpr" or "lazbuild -B Bru2.lpr".
  4. To build the graphical version from the command line, run the command "lazbuild -B Bru2Nii.lpr". Note by default OSX will compile to 32-bit Carbon. If you have a recent SVN of Lazarus (50307 or later) you can compile as 64-bit Cocoa with "lazbuild ./Bru2Nii.lpr --cpu=x86_64 --ws=cocoa --compiler="/usr/local/bin/ppcx64""
  5. You may optionally strip you executables to make them require less disk space, e.g. "strip ./Bru2Nii", "strip ./Bru2" - the compiler will probably do this automatically for Windows or Linux, but not OSX (due to the debugger).
