Can you direct me to any papers or tutorials? Very sorry to be so long to respond. The reason was, that I have been working on some code that may help. The current version of marsbar - in CVS (http://marsbar.sf.net/cvs.html) - contains a variety of menu options in the results interface to define event types (for example combining events across sessions), to show fitted event time courses from the SPM model, and to estimate event-related FIR time courses. I have just finished writing the code, so would appreciate feedback from anyone who feels like testing it. For tutorials etc, you could try Russ Poldrack's matlab file tutorials: http://www.poldracklab.org/spm/tutorials/ I would also recommend the Dale 1999 paper in Human Brain Mapping as an introduction to the theory - although it is not written in SPM-compatible language. I have somewhere a journal club presentation on that paper; if anyone wants a copy, let me know. Best, Matthew |
