fmrii is a C library provides a number of models for working with Functional Magnetic Resonance Imaging (fMRI) data. At this stage it provides:
the regular and log space balloon models,
simple neural models,
simple experimental input models, and
compound models which combine any number of the above.
All of the models are compatible with probabilistic methods provided by the dysii Dynamic Systems Library for model fitting and parameter estimation.
Features are added to the library as needed, so that it does lack some completeness. What is included, however, is well documented and tested, and may be considered fairly sound for research purposes.
The library has been optimised for performance, while maintaining a modularity and generality that makes it suitable for a wide range of applications within the fMRI domain.
