Thanks Niels and Moises! Niels, the documentation in the Github repo makes setting up the overlay look pretty straight-forward. I did take a look at some of the code – it looks like the fsl_sub script has been altered to use qsub for Torque. Do you suggest deploying this overlay as-is? Or do you have any specific change recommendations for these scripts?
Moises, could you please tell me what kind of memory usage I should anticipate when running this with HCP diffusion data after I set it up? Thanks a lot!

I also want to know a couple other things - is Sun Grid Engine (SGE) a particular requirement to ensure bedpostx internally splits the slices among all available CPU cores? Or will something like Torque and Maui also be fine? The system administrator in my college says that we already have Torque and Maui and so it’ll be much quicker to have that set up for me. If Torque and Maui will also be fine, could you also share the relevant changes that we’d have to make to any files/anything else to successfully and quickly run bedpostx for HCP diffusion data? And on a slightly different note, what kind of memory usage should I anticipate when I run this for HCP diffusion data?

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!
