pedFamilias vs pedprobr
A side-by-side editorial comparison of pedFamilias and pedprobr — release velocity, themes, recent moves, and the top alternatives to consider.
pedFamilias vs pedprobr: at a glance
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.
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.

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.
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.

Frequently asked questions
What is the difference between pedFamilias and pedprobr?
They serve adjacent needs but don't currently overlap on shipped themes. pedFamilias and pedprobr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is pedFamilias better than pedprobr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. pedFamilias and pedprobr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
