Last week we released version 1.11 of BrainLiner.jp. This release includes a complete redesign of the site and new HTML5 web data previewer.

Yusuke Fujiwara has just open-sourced his variational Bayesian CCA library for matlab. This library uses data from Miyawaki’s 2008 paper and is available on github:

We are happy to announce that we released v.1.06 of BrainLiner.jp, our lab’s web portal for sharing neurophysiological data, with an emphasis on facilitating brain-machine interface (BMI) research. This release was in development for several months and includes the following key updates:

• “Experiments” are now called “Projects”
• References related to your experiment, such as published journal articles, can now be added
• An area to enter contact information that will be made public has been added
• Channels inside Neuroshare data files can now be edited to include meta-information, such as whether they are data channels or stimulus labels
• For data files that have less than 200 channels, we compute correlation matrices and principle-component variance graphs and display these on a new “View Statistics” page, associated with each relevant data file
• By default up to 20 channels are displayed in the Flash-based data previewer

Please give us your feedback and new ideas!
