Software

A minor update to the fmrii fMRI Modelling Library has been released, bringing it up to date with the latest version (1.1.0) of the dysii Dynamic Systems Library.

Version 1.1.0 of the dysii Dynamic Systems Library is now available. The primary feature of the new release is an overhauled implementation of the parallel particle filter and smoother, with new distributed storage capability. Serialization of distributions is also now available, working towards a more sophisticated framework for data management.

Specific changes include:

• Overhauled parallel implementations from master-slave to SPMD.
• Improved particle smoother with further parallelisation.
• Added distributed storage of mixtures.
• Added Gaussian mixture distributions.
• Added serialization of probability distributions.
• Fixed Wiener process variance bug.

See the updated documentation and VERSION.txt file in the new distribution for more information.

Forums are now available, particularly for discussion of Tint, but anything goes really. This should better facilitate feature requests, bug reports, support and so forth, rather than relying only on comments to my posts (like this one…). Please feel free to contribute!

I’ll pretty up the style at some point to match the rest of the site, but for now the most important thing is that the functionality is there.

I’ve set up SourceForge projects for tint, dysii and fmrii, initially to handle file releases. This should relieve some of the bandwidth drain on this site. I’m considering moving Subversion repositories onto SourceForge also, to facilitate collaboration on some of this work in future.
