This PR splits the tractography section from the diffusion derivatives document, so that #5 is easier to merge. The new ``05-diffusion-derivatives-tractography.md`` file will remain orphaned, but kept there as a base for the time we tackle tractography. It shouldn't be merged into the derivatives branch until it is ready.

Is that really how nifti is capitalized?

Should we say more about the file formats used to store tractograms?

Hey @francopestilli - is that the right terminology? "Tracogtram" refers to any subset, and "whole brain" is called "connectme" ?

Does ENS really belong under the "global" category? Arguably, it can't generate anything that's not in one of the local tractograms in the ensemble?

We need to add "pft" (particle filtering tractography, see Girard et al., 2014)

Is this the number of streamlines stored in the file?
|
Do you want this merged ASAP, and come back to these comments later? |
Yup, could you open a PR with your comments after this is merged? |

Oh - no big green button! Looks like I don't have the permissions to merge this. :trombone: |

Fixed that! |
