One should use 3 fibers for HCP data however. Matt.

One large slice of HCP diffusion data takes about 4 hours on a single CPU core (modern processors have several cores) using the default parameters (2250 MCMC iterations, 2 fibres estimation). HCP data has about 90 slices with diffusion information, although some of them are small and are processed in few minutes. If you have a queue system, such as SGE, you can send each slice to a different CPU core. Moises.

Also, what are the recommended hardware specs to run bedpostx on HCP data? Thanks!
