Tools for community annotation of event-rich data.


CTAGGER is a MATLAB/Java toolbox that implements a user-friendly, semi-structured and expandable strategy for event annotation in dynamic brain imaging and other time-series. To facilitate common labeling and comparison across data collections and laboratories, an individual’s annotation can be collected in a common community database to encourage annotation reuse. The tools allow the creation of multiple event overlays to facilitate the reuse and combination of brain imaging data for multiple analyses.

The tagging tools represent the tagging hierarchy in XML format, following the HED Specification (Hierarchical Event Descriptor) developed by Shamlo and others at of UCSD. (See for more information.)
