fmrigds

Lazy, format-agnostic group analysis for fMRI.

Details

fmrigds provides a common Group Data Set (GDS) abstraction for first-level fMRI outputs together with a lazy, plan-based workflow for group analysis. The package centers on a compact public grammar:

• gds() to open supported sources and create a plan

• subset(), derive(), align(), mask(), map_to(), reduce(), posthoc(), and write_out() to describe analysis steps

• compute() to execute the plan and return a realised GDS

Core capabilities include:

• Constructors for GDS objects and spaces

• Storage adapters (tabular, NIfTI, HDF5, fmristore)

• Statistical derivations and variance propagation helpers

• Reducer and post-hoc registries for group and meta-analytic workflows

• Provenance-aware export and inspection helpers

See the package reference and vignettes for supported workflows and release guidance.
