MRIcron / NPM / dcm2nii

About

MRIcron is a viewer for brain imaging data.

Installing

You can download the software from several locations:

• Download from NITRC.
• Download from Github.
• Run the following command to download the latest version for Linux, Macintosh or Windows:
  • curl -fLO https://github.com/neurolabusc/MRIcron/releases/latest/download/MRIcron_linux.zip
  • curl -fLO https://github.com/neurolabusc/MRIcron/releases/download/MRIcron_macOS.dmg
  • curl -fLO https://github.com/neurolabusc/MRIcron/releases/latest/download/MRIcron_windows.zip

Once you have downloaded and extracted the software, you may want to visit the wiki for usage advice.

Future

MRIcron is robust and stable, but development efforts have moved to MRIcroGL. The primary disadvantage of MRIcroGL is that it requires support hardware accelerated OpenGL 3.3 graphics. Therefore, MRIcron remains useful for users of older computers or when connecting to remote supercomputer clusters. These users may also consider fsleyes which can be set up to only require OpenGL 1.4 and indirect rendering.

The latest releases of MRIcron only include the MRIcron viewer and the dcm2niix image converter. Once upon a time, the software was distributed with statistics (NPM) and legacy image converter (dcm2nii). One can still download old releases of MRIcron from NITRC or compile these legacy tools (see next section).

NPM is a tool for non parametric analysis of neuroimaging lesion data. dcm2nii is designed for converting the complicated DICOM format used in medical imaging to the simple NIfTI format preferred by scientists. These tools are mature and hopefully robust but no longer in active development.

• MRIcron development has moved to MRIcroGL
• NPM development has been moved to NiiStat
• dcm2nii development has been moved to dcm2niix

Compiling your own software

You can build MRIcron using Lazarus.

• Launch Lazarus and open the project.
• Choose Run/Run to build and execute the program
