glyenzy vs pedprobr
A side-by-side editorial comparison of glyenzy and pedprobr — release velocity, themes, recent moves, and the top alternatives to consider.
glyenzy vs pedprobr: at a glance
What is glyenzy?
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.
What is pedprobr?
pedprobr is the likelihood engine, and it keeps finding ways to compute what it previously could not.
pedprobr computes pedigree likelihoods for the ped suite. Version 1.1.0 updated its loop handling to match pedtools 2.11.0, including founder and repeated loop breakers, and improved the peeling algorithm with single-child shortcuts and lower memory use. Version 1.0.0 was the other expansion: special lumping lets markers with mutation models that are un-lumpable in the Kemeny-Snell sense be lumped anyway in certain cases, with alleleLimit as a fallback for the rest.

Glycan biosynthesis as a traceable enzyme graph, now including sulfation and gaps it can bridge.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
pedprobr
0.0ANALYTICS
pedprobr is the likelihood engine, and it keeps finding ways to compute what it previously could not.
◆ Current state
pedprobr computes pedigree likelihoods for the ped suite. Version 1.1.0 updated its loop handling to match pedtools 2.11.0, including founder and repeated loop breakers, and improved the peeling algorithm with single-child shortcuts and lower memory use. Version 1.0.0 was the other expansion: special lumping lets markers with mutation models that are un-lumpable in the Kemeny-Snell sense be lumped anyway in certain cases, with alleleLimit as a fallback for the rest.
◆ Where it's heading
Every significant release here removes a class of computation that used to be infeasible, either by making a marker lumpable or by making a loop breakable. The rest is steady peeling-algorithm optimization, which has been reducing memory footprint release after release since 0.9.2. The newly added .diagnostics option suggests the peeling internals are now complex enough that the maintainer needs to inspect them.
◆ Prediction
Since special lumping is documented as covering only some cases so far, expect further lumping situations to be implemented as pedmut adds them.
