About SumsDB
SumsDB (the Surface Management System DataBase) provides access to a growing body of neuroimaging and related data. WebCaret software provides online data visualization for datasets in SumsDB.
Five Main Categories of Data Based on Data Type and Usage
Atlas Datasets
- Surface and volume data
- Structural and functional data
- Data on cerebral cortex and cerebellar cortex
- Human data – normal and neurological/psychiatric disorders
- Nonhuman primate data: macaque, chimpanzee, gorilla
- Rodent: mouse and rat data
Searchable Stereotaxic Foci and fMRI Maps
- Published data, curated and customized for data mining
- Over 25,000 sterotaxic foci from nearly 1,000 published studies
Publication Associated Datasets
- Underlay key figures in specific online publications:
- Individual subject data and population data mapped to atlases
Project-Related Datasets
- From various ongoing projects that serve archival purposes and sharing with selected collaborators
- Data from FreeSurfer, CIVET, and other brainmapping software besides Caret
Tutorials
- Documents and associated datasets from tutorials for both SumsDB/WebCaret and Caret.
Data Access and Security
- SumsDB provides multiple levels of data access and security
- Free (public) access (e.g., for data associated with published studies)
- Data access restricted to collaborators in different laboratories
- Owner-only access for work in progress
Data Organization
- Download data as individual files or as collections (‘spec files’) customized for offline analysis in Caret
WebCaret
- WebCaret provides online ‘Caret-style’ visualization without software or data downloads:
- WebCaret ‘scenes’ facilitate rapid visualization of complex combinations of data
- Bi-directional links between online publications and WebCaret/SumsDB provide:
- Links from figures in online journal article to corresponding scenes in WebCaret
- Links from metadata in WebCaret directly to relevant online publications and figures
Searching and Data Mining
- Searching and data mining options using SumsDB and WebCaret:
- Search by data type, filename, associated metadata (text-based search)
- Spatially based queries
- Proximity to stereotaxic coordinates
- Overlap with selected fMRI activations (metric files)
- Overlap with identified cortical areas (paint files)
- Searches can be applied to:
- Currently loaded datasets
- ‘Processed’ datasets
- All public SumsDB data
- Restricted access data
- Search results can be:
- Viewed in WebCaret
- Combined with other loaded data sets
- Downloaded directly
Hardware
- SumsDB and WebCaret on a Linux cluster housed in the Electronic Radiology Laboratory in the Washington University Department of Radiology. * * Automatic data backup and recovery are handled through a Network Attached Storage system.
