What is ieegio?

ieegio's first release lands electrode trajectory burning and a WebGL-free surface plot

ieegio handles file I/O and volume manipulation for intracranial EEG and neuroimaging data in R. Only one release is on record, 0.1.0 from May 2026, so there is no cadence to read yet. Its content is a mix of new volume-authoring capability and format-level correctness fixes.

What is pedFamilias?

pedFamilias exists to read one legacy file format, and it has that job nearly finished.

pedFamilias holds the Familias file interoperability code that was split out of forrel, principally readFam() and writeFam(). The visible history is short and narrow: URL paths accepted as input, a deduplicate option for files produced by the Familias DVI module, better handling of extra individuals, and a fallback mutation model when stabilization fails. The most recent release is explicitly maintenance.

ieegio's first release lands electrode trajectory burning and a WebGL-free surface plot

◆ Current state

ieegio handles file I/O and volume manipulation for intracranial EEG and neuroimaging data in R. Only one release is on record, 0.1.0 from May 2026, so there is no cadence to read yet. Its content is a mix of new volume-authoring capability and format-level correctness fixes.

◆ Where it's heading

The release points at two audiences at once: burn_curve() writes electrode trajectories — depth/sEEG leads, DBS shafts — into a volume from start and end positions in native RAS coordinates, with a merge mode so trajectories compost onto an existing volume rather than overwriting it. Separately, a base R graphics plot method for surfaces provides a path for environments without WebGL, where the default r3js renderer cannot run. Format work covers BCI2000 and BrainVision channel lookup by label and a quaternion handedness fix aligning with FreeSurfer conventions.

◆ Prediction

A single release gives no basis for predicting cadence. The FreeSurfer alignment and multi-format channel handling suggest interoperability with established neuroimaging toolchains is the near-term priority.

pedFamilias exists to read one legacy file format, and it has that job nearly finished.

◆ Current state

pedFamilias holds the Familias file interoperability code that was split out of forrel, principally readFam() and writeFam(). The visible history is short and narrow: URL paths accepted as input, a deduplicate option for files produced by the Familias DVI module, better handling of extra individuals, and a fallback mutation model when stabilization fails. The most recent release is explicitly maintenance.

◆ Where it's heading

This is a package with a bounded remit. The format it parses does not change, so releases arrive only when someone encounters a file it mishandles, and the fixes are correspondingly specific. The interesting movement is upstream instead: forrel finally removed its deprecated readFam() re-export in 1.9.0, completing the split that created this package.

◆ Prediction

Expect continued low-frequency maintenance driven by real-world .fam files rather than any planned feature work.
