Dear Frank,

   I am trying to use DIPY to perform RecoBundles. One of the required steps is registration, which depends on the whole-brain tractogram of the HCP1065 Population-averaged Tractography Atlas or, alternatively, on understanding how the HCP1065 was registered. I have not been able to find this whole-brain tractogram online, whereas the HCP842 tractogram is provided directly in DIPY. Therefore, understanding the registration procedure for HCP1065 seems especially important.

  According to the information on https://brain.labsolver.org/hcp_template.html, the HCP1065 registration is based on the nonlinear ICBM152 2009a space. Does this mean that all bundles in the atlas (https://github.com/frankyeh/data-atlas/releases/download/hcp1065/hcp1065_avg_tracts_trk.zip) have also been nonlinearly registered to the ICBM152 2009a space?

Kind regards,
Darren
