pedtools vs qcTAF
A side-by-side editorial comparison of pedtools and qcTAF — release velocity, themes, recent moves, and the top alternatives to consider.
pedtools vs qcTAF: at a glance
What is pedtools?
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.
What is qcTAF?
qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time
qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.

pedtools rewrote loop breaking and made a class of pedigrees analyzable for the first time.
◆ Current state
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.
◆ Where it's heading
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().
◆ Prediction
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.

qcTAF is building an automated checklist for reproducible fisheries assessments, one criterion at a time
◆ Current state
qcTAF performs quality control on TAF (Transparent Assessment Framework) analyses, the workflow standard used for ICES fisheries stock assessments. It launched in February 2026 with eight checking functions and a README listing ten criteria that define a complete TAF analysis. Three releases followed within four months, all adding checks or tightening existing ones.
◆ Where it's heading
Each release converts more of the informal completeness checklist into executable checks. February added relative-path and script-existence checks; late February added data and software declaration checks plus two new completeness criteria covering initial-versus-boot data identity and DATA.bib declarations; May added qc.any.scripts.exist() and made qc.only.relative.paths() treat /home/ as absolute. Function naming is being revised as the set grows, with renames in every release so far.
◆ Prediction
With the naming churn ongoing and criteria still being added, the next release most likely continues both. The package appears to be tracking a moving definition of TAF completeness rather than a fixed spec.
