That page appears to be down for the moment. We’ll get it fixed. The Echo Spacing for the dMRI from the Lifespan1a pilot was 0.69 ms. (Although, FWIW, if you already processed your data using 0.78 ms, it doesn’t matter in this particular case. You’ll still get a completely correct distortion correction of the dMRI data).

I have done my best, however could not find the value of echo timing for topup on the internet which is explicitly declared for it. I used 0.78 ms as the value of echo timing to implement topup and obtained priliminary results (showed in Attachment 1). Please inform me the actual value of echo timing. Could I ask for Full scanning protocols of HCP-lifespan-pilot-1a diffusion and fMRI data?

This will handle the combination for dMRI. For fMRI the data can be combined after sICA+FIX cleanup after demeaning (and perhaps variance normalizing) it. Given that you may not wish to deal with preprocessing the lifespan pilot data, you might be better off exploring your hypothesis in the already preprocessed young adult HCP data and waiting for the lifespan data release of preprocessed data.

For testing my hypothesis inspireed by pediatric neurosurgery practice, I attempt to use the data of HCP lifespan pilot 1a to expore the function of some brain region. Although I spent about several monthes searching the solution for combining LR.nii and RL.nii of dMRI or fMRI data, I find I can’t do it. Could you please send me the solution you recommend? Thank you very much!
