Viewing FSL results with SPM and vice versa

A growing number of efforts are emerging in the neuroimaging community to increase reproducibility of research findings (e.g. [1,2]). In an attempt to facilitate publishing of neuroimaging data and metadata, the NeuroImaging Data Model (NIDM) defines a set of specifications based on semantic web technologies. The NIDM-Results specification was recently introduced, providing a machine-readable representation of mass univariate statistical results, including extensive metadata and key images summarising the findings [3] . The main motivation for NIDM-Results was to make publishing of neuroimaging results data and metadata as effortless as possible and hence facilitate compliance with statistical guidelines (e.g. [4] ), increase reproducibility and enable image-based meta-analyses. An NIDM-Results pack is a ZIP archive containing a Resource Description Framework (RDF) metadata file, which stores provenance information, alongside several NIfTI images and CSV files. NIDM-Results packs can be generated via NIDM-Results exporters, which are available for Statistical Parametric Mapping (SPM) [5] and the FMRIB Software Library (FSL) [6] . However few tools exist to read and display NIDM-Results. This is hindering the distribution and acceptance of NIDM within the neuroimaging community. Here, we introduce two NIDM-Results viewers, one each oriented for users accustomed to SPM and FSL, two of the most widely-used neuroimaging analysis softwares [7] .
