ieegio vs rpymat: at a glance
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 rpymat?
After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together
rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.

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.

After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together
◆ Current state
rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.
◆ Where it's heading
The work is about surviving the seams between two runtimes. 0.1.9 addresses OpenMP double-initialization — the error users hit when R's OpenMP and conda's disagree — by setting KMP_DUPLICATE_LIB_OK as a compromise, and adds fix_omp_conflict() to symlink over conda's built-in version as the recommended real fix. The caveat is stated plainly: users must re-run it whenever R is updated, and the ABI versions must match. Earlier releases followed the same pattern, with 0.1.2 fixing segfaults from incompatible BLAS between numpy and R.
◆ Prediction
The recurring theme across releases is native library conflicts between the R and conda stacks, so further releases are likely to keep patching that surface as Python versions move. The three-year gap makes cadence unpredictable.
