SDM exploration of the results


Help Thresholding
the results
Results from previous calculations can be thresholded obtaining meta-analytic peak coordinates, clusters breakdowns and NIfTI (Analyze-compatible) images which will be authomatically open in an MRIcron template (see Settings).
Help Multimodal
Results of two meta-analyses of studies conducted in different modalities, e.g. VBM and fMRI, may be combined in a single map.

Masks are used in SDM to extract the values in a voxel or region from all studies and analyses. Masks are saved in separate mask_*.nii.gz files, which can be used in more than one meta-analysis.
Help Extracting
masked values
Values in a mask (including a coordinate or region) can be extracted from all studies and analyses.
