A side-by-side editorial comparison of glyenzy and pedtools — release velocity, themes, recent moves, and the top alternatives to consider.
Glycan biosynthesis as a traceable enzyme graph, now including sulfation and gaps it can bridge.
glyenzy infers which enzymes could have produced a glycan and traces biosynthetic routes to it, backed by curated per-enzyme rules for human glycosyltransferases and, since 0.7.0, twelve sulfotransferases. Biosynthesis functions return typed network objects that keep their igraph interface while supporting layered DAG plots with glycan nodes and labelled enzyme edges. Where no concrete enzyme covers a step, bounded virtual transitions bridge the gap and are marked so users can see which edges are inferred rather than enzymatic.
pedtools rewrote loop breaking and made a class of pedigrees analyzable for the first time.
pedtools is the foundation of the ped suite, holding the pedigree data structures every other package builds on. Version 2.11.0 revamped the loop breaking algorithm so founders can serve as loop breakers and one individual can break several loops, which makes likelihood calculations possible in pedigrees that previously could not be handled at all. Loop detection also became mandatory and faster, and the surrounding releases have steadily added query and construction helpers.

Two kinds of release alternate here. One is enzyme curation, a steady stream of rule corrections for the FUT, MAN1A and MGAT families and removals where an enzyme turned out to act only on glycolipids, which is the unglamorous accuracy work a rule-based inference engine lives on. The other is turning biosynthesis output into a first-class object: paths became networks, networks became typed with plotting support, and targets became a marked vertex attribute. The package moves in lockstep with its siblings, pinning glyrepr 0.13.0 and glymotif 0.17.0 as those refreshed their data and matching APIs, and the latest release already speaks glydraw 0.8.0's orientation values.
The paucimannose N-glycan support dropped in 0.7.0 is the obvious loose end, with users told to stay on 0.6.3, so a reinstated implementation is a plausible next move. Beyond that the virtual-step machinery is new enough that its heuristics, particularly the inferred step limits added in 0.8.1, should keep being tuned.

The package has been working toward this for over a year. Version 2.8.0 replaced the igraph-based loop breaker with a custom implementation, 2.8.1 made findLoopBreakers() substantially faster in large pedigrees, and 2.11.0 rewrote the algorithm outright. The new methods ship disabled by default while downstream packages catch up, which is a deliberately staged rollout rather than a flag day. Alongside that, the additive work is small, well-scoped helpers: children2(), addSibling(), isHomozygous(), trim(), nChildren().
Expect the new loop breaking methods to become the default once pedprobr, forrel, and dvir have all shipped support for them, since the only stated reason for the opt-in flag is downstream readiness.
