glydet vs pedFamilias: at a glance
What is glydet?
glydet is rebuilding its glycan trait vocabulary on top of someone else's container.
glydet derives glycan-derived traits from glycomics and glycoproteomics data. The 0.12.x line spent its releases absorbing glyexp's container migration: derive_traits(), quantify_motifs(), and add_meta_properties() now accept GlycomicSE and GlycoproteomicSE natively, with the legacy experiment() path kept only for backward-compatible return types. The substantive feature work sits one release back in 0.11.0, which added sialic acid linkage traits and three published trait sets.
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.

glydet is rebuilding its glycan trait vocabulary on top of someone else's container.
◆ Current state
glydet derives glycan-derived traits from glycomics and glycoproteomics data. The 0.12.x line spent its releases absorbing glyexp's container migration: derive_traits(), quantify_motifs(), and add_meta_properties() now accept GlycomicSE and GlycoproteomicSE natively, with the legacy experiment() path kept only for backward-compatible return types. The substantive feature work sits one release back in 0.11.0, which added sialic acid linkage traits and three published trait sets.
◆ Where it's heading
Two threads run in parallel here. One is infrastructure: track glyexp's Stage II migration, drop the underscore matrix interfaces, and converge on a single trait column in var_info. The other is content: keep adding named trait sets from the literature (Clerc 2018, Li 2025, Fu 2026) so users cite a set rather than hand-roll definitions. The LLM-backed explain_trait() and make_trait() helpers are becoming provider-agnostic rather than deeper.
◆ Prediction
The trait catalogue is the growth area, so expect more published trait sets added as named functions, and the deprecated basic_traits() and all_traits() aliases to be removed once the container migration settles.
pedFamilias
0.0ANALYTICS
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.
