fMRIPrep 23.0.0

We have just released fMRIPrep 23.0.0, which includes a number of improvements.

There are some new features highlighted in the release notes below, but please do test this out if susceptibility distortion correction (SDC) has been causing troubles for you in recent releases.

If you are still seeing issues, please use the new Software Support - Neurostars category and make sure to tag with fmriprep, sdc and include โ€œ23.0โ€ in the title.

Release Notes

This release adds improvements for workflows targeting the fsLR grayordinate space. Namely, morphometric (curvature, sulcal depth and cortical thickness) measures are output as .dscalar.nii files and high-variance voxels can be excluded from the resampling step using --project-goodvoxels.

Additionally, T2w images are now resampled to the T1w-defined subject space if FreeSurfer reconstruction is used. If multiple T2w images are provided, they are merged into a single image first.

PEPolar fieldmaps with R/L phase-encoding directions or in non-standard orientations are now better supported. We continue to work toward better support for more SDC configurations.

23.0.0 supports FreeSurfer 7.3.2, which is now bundled in the Docker image.

ICA-AROMA support will be removed in 23.1.0.
