Overview
Statistical Parametric Mapping (SPM) is a software package designed for the analysis of brain imaging data sequences. It's built on the concept of spatially extended statistical processes to test hypotheses about functional imaging data obtained through techniques like fMRI, PET, SPECT, EEG, and MEG. SPM allows researchers to analyze data from different cohorts or time-series from the same subject. Key functionalities include preprocessing, statistical modeling using the general linear model, and statistical inference to identify significant brain activation patterns. Being open-source, SPM promotes collaborative development and standardized analysis across laboratories, allowing researchers to extend the core functionality. The software provides online tutorials, documentation, and a discussion list, fostering a community-driven environment.
