Catalog & visualization notes
Scope
The gallery contains map-based models from the repository’s multivariate signature collection, with named predictive and statistical-support maps. Connectivity-edge models, network-coefficient-only models, masks that are not predictors, and unavailable maps are excluded. Fibromyalgia maps are withheld from this web build while the repository’s request-only statement is reconciled with the files present.
Display thresholds
By default, the strongest 35% of positive values and strongest 35% of negative magnitudes are shown. Percentages are calculated independently among finite nonzero values of each sign, using a linearly interpolated percentile cutoff. All ties at the cutoff are retained, so exact retained fractions can differ. Zero percent hides that sign; 100% shows every finite nonzero value. Positive and negative controls may be adjusted separately or synchronized. Absolute thresholds use the map’s physical value units.
These are display thresholds, not significance tests. For supplied thresholded or bootstrap maps, the controls act on that map’s remaining values; they cannot restore weights absent from the source. Predictive weights and statistical support maps are explicitly distinguished.
Volumes and downloads
Existing 3D NIfTI downloads preserve the original file content, with gzip decompression when necessary. Analyze pairs are converted to NIfTI with values and affine preserved. 4D files are split into named components without spatial resampling. Every catalog map links to its original repository file. Quantile calculations and interactive rendering use floating-point copies; changing the display never changes downloaded values.
Atlas and cortical surface
The orthographic viewer reuses CANlab’s NiiVue wrapper and its CANlab2024 atlas region naming and highlighting. Surface views use HCP S1200 MSMAll fsLR 32k midthickness meshes (left and right), with trilinearly sampled volume values in world coordinates. This is an approximate MNI visualization; no nonlinear registration is performed. Exact MNI template variants are not documented for all source maps. Inspect the slices for anatomical alignment and subcortical features.
The same voxel-derived cutoffs are applied on the surface. Interpolation can change the proportion of visible surface vertices. Surface projections are display derivatives and must not be substituted for a volumetric predictive model.
Reproducibility and performance
The site builds static map assets, percentile tables, surface values, previews, and individual study pages in advance. Shared viewer code, atlas, anatomy, and meshes are versioned and cached. Only the selected map is loaded interactively. MATLAB and server-side computation are not required to serve the gallery.
Credits and use
Cite the original publication linked on each study page and follow the source’s usage terms. CANlab viewer code is distributed under its accompanying license; NiiVue is BSD-2-Clause licensed. HCP S1200 meshes are distributed with CanlabCore; see HCP data release documentation. The filter interaction follows the Science of Placebo database: OR within categories and AND across categories.
Repository, source data, and documentation ↗
Graphical navigation and anatomical names
The default tree groups studies by their first curated domain tag; filtering still considers all tags. Tree branches indicate categories, not empirical similarity or relationships between weights. The labeled semantic graphs of Huth et al. (2012) inspired this browsing approach. Tiles remain available as an alternative. The steel-gray and seafoam palette follows the neutral-base, purposeful-accent approach of IBM Design Language.
Search or download all 518 descriptive parcel names. Glasser cortical names follow the 2016 neuroanatomical supplement (area names table); other regions follow CANlab source dictionaries and Brainstem Navigator. Coarse parcel components and sources are retained per row. Spelling is normalized where obvious; the displayed hemisphere takes precedence over inconsistent source rows. The atlas voxel data remain unchanged.
Thumbnail overlays are restricted to the repository MNI152NLin2009cAsym binary brain mask, resampled to each map by nearest-neighbor interpolation in world coordinates. This is a thumbnail-only display mask and an approximate template alignment. Preview slice selection also uses masked weights. Inferno and winter match the pinned viewer palette; both signs retain 35%. Surface lighting uses NiiVue’s matte shader without specular highlights.
