The BrainLiner Platform for Sharing, Searching, and Previewing Time-Aligned Neurophysiological Data

Performing experiments and recording neurophysiological data requires substantial resources. At the same time, data-driven science requires large amounts of data in order to build statistical models and study the relationships between tasks and complex brain activity patterns. Thus to maximize returns on invested resources and to conduct meaningful research, it is important for scientists not only to publish descriptions about their research, but also to share the data used in such publications.
BrainLiner.jp was launched as part of the Japanese Strategic Research Program for Brain Science (SRPBS) to share time-aligned neurophysiological and stimulus data. Using our portal, scientists from all over the world can freely share data that is time-aligned to behavioral information, in a standardized file format. We allow users to upload data as Neuroshare or matlab files in a standardized format. We then convert uploaded matlab files into Neuroshare (.nsn) files and uploaded Neuroshare files into matlab files automatically when a user uploads a data file.
BrainLiner.jp has supported text-based search of project descriptions and documents since the first release. However, we recently added a data-driven similarity search feature to search for data that are similar to input data. Users can select interesting data patterns and then, using our data search, can find similar data that share a similar pattern.
Our data-drive search is implemented as a web service that is accessible programmatically, allowing developers with API access to incorporate our data similarity search into their analyses.
We recently re-implemented our data previewer in HTML5, to allow people without Flash to preview data. As with the data-driven search, the HTML5 viewer is implemented as a modular web service, which is hoped to be extensible in the future.
Finally, to ease data sharing and use, we completely redesigned and reimplemented our web portal with a simpler and more responsive interface.
