SPM is made freely available to the [neuro]imaging community, to promote collaboration and a common analysis scheme across laboratories. The software represents the implementation of the theoretical concepts of Statistical Parametric Mapping in a complete analysis package.

The SPM software is a suite of MATLAB (The MathWorks, Inc) functions and subroutines with some externally compiled C routines. SPM was written to organise and interpret our functional neuroimaging data. The distributed version is the same as that we use ourselves.


SPM is free but copyright software, distributed under the terms of the GNU General Public Licence as published by the Free Software Foundation (either version 2, as given in file, or at your option, any later version). Further details on "copyleft" can be found at In particular, SPM is supplied as is. No formal support or maintenance is provided or implied.

Current version: SPM12

The current version is SPM12 and was released 1st October 2014. This provides a major update to the SPM software, containing substantial theoretical, algorithmic, structural and interface enhancements over previous versions.
