Release notes

New feature release in the 23.2.x series.

This release wraps up a significant refactor of fMRIPrep. The main new features can be used with the --level and --derivatives flags.

The --level flag can take the arguments minimal, resampling or full. The default is full, which should produce nearly the same results as previous versions. minimal will produce only the minimum necessary to deterministically generate the remaining derivatives. resampling will produce some additional derivatives, intended to simplify resampling with other tools.

The --derivatives flag takes arguments of the form name=/path/to/dir, for example --derivatives anat=$SMRIPREP_DIR. If provided, fMRIPrep will read the specified directories for pre-computed derivatives. If a derivative is found, it will be used instead of computing it from scratch. If a derivative is not found, fMRIPrep will compute it and proceed as usual.

Taken together, these features can allow a dataset provider to run a minimal fMRIPrep run, targeting many output spaces, while a user can then run a --derivatives run to generate additional derivatives in only the output spaces they need. Another use case is to provide an precomputed derivative to override the default fMRIPrep behavior, enabling easier workarounds for bugs or experimentation with alternatives.

Additionally, this release includes a number of bug fixes and improvements. This release adds support for MSM-Sulc, improving the alignment of subject surfaces to the fsLR template. This process is enabled by default, but may be disabled with the --no-msm flag.

This release resolves a number of issues with fieldmaps inducing distortions during correction. Phase difference and direct fieldmaps are now masked correctly, preventing the overestimation of distortions outside the brain. Additionally, we now implement Jacobian weighting during unwarping, which corrects for compression and expansion effects on signal intensity. To disable Jacobian weighting, use --ignore fmap-jacobian.

Finally, a new resampling method has been added, to better account for susceptibility distortion and motion in a single shot resampling to a volumetric target space. We anticipate extending this to surface targets in the future.
