I will note that RC1 indicated that X, Y, Z were to become TransX, TransY and TransZ as well. This was not generally discussed and made it into RC1 as a function of copy-paste. I think the impact here would be fairly far reaching for little gain, so I'm leaving that off this list until the discussion is resolved.

Metadata

a/tCompCor columns must have an associated Method metadata. We can probably do this with:

fmriprep/desc-confounds_regressors.json:

{
    "aCompCor00": {"Method": "aCompCor"},
    "aCompCor01": {"Method": "aCompCor"},
    ...
}

GlobalSignal, WhiteMatter and CSF should have the following metadata:

{
    "GlobalSignal": {"Method": "Mean"},
    "WhiteMatter": {"Method": "Mean"},
    "CSF": {"Method": "Mean"}
}

AROMAaggrCompXX should indicate ICA-AROMA version. Not sure whether "Method" can be a dict with "Name" and "Version", or what.

Is this one done with #1586?

[oesteban]

Done for CompCor only. Added two unitary issues addressing each type of regressor separately.
