forrel vs pedFamilias

forrel vs pedFamilias: at a glance
What is forrel?
forrel is getting faster at the simulations forensic kinship work actually spends its time on.
forrel handles forensic pedigree analysis: kinship likelihood ratios, profile simulation, relationship checking, and missing person calculations. Version 1.9.0 synced with pedtools 2.11.0's loop handling, which the release notes credit with enabling complex pedigrees that were previously intractable, and moved profileSim() to mirai for parallelism. It also added fEstimate() for inbreeding coefficients and parentChildLikelihood() as a fast path for the simplest case.
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.

forrel is getting faster at the simulations forensic kinship work actually spends its time on.
◆ Current state
forrel handles forensic pedigree analysis: kinship likelihood ratios, profile simulation, relationship checking, and missing person calculations. Version 1.9.0 synced with pedtools 2.11.0's loop handling, which the release notes credit with enabling complex pedigrees that were previously intractable, and moved profileSim() to mirai for parallelism. It also added fEstimate() for inbreeding coefficients and parentChildLikelihood() as a fast path for the simplest case.
◆ Where it's heading
Two long threads run through the window. One is making the common operations cheap: faster simulations through reorganized likelihood calculations, a dedicated parent-child path, dropped map attribute preservation, log-likelihoods to avoid underflow in kinshipLR(). The other is making relationship checking presentable, with checkPairwise() growing ggplot2 and plotly output, verbal relationship descriptions, and bootstrap p-values. Reference data is maintained alongside both, with the FORCE SNP panel completed and an X-chromosomal counterpart added.
◆ Prediction
With profileSim() on mirai and the loop handling synced, the next likely step is extending mirai parallelism to the other simulation-heavy functions such as exclusionPower() and the bootstrap in checkPairwise().
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.
