What is KLINK?

Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.

KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.

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.

Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.

◆ Current state

KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.

◆ Where it's heading

The direction is from fixed panel toward general instrument. Hard-coded linkage pairs gave way to dynamic pairing, the built-in map grew from 18 to 50 markers, the map itself was then moved out to the norSTR package, and the app now accepts custom maps in several file formats and decimal conventions. Method capability tracks the upstream pedsuite rather than KLINK itself: special lumping in pedprobr and pedmut is what allowed complex mutation models in common pedigrees, and the newest release pins pedtools 2.11.0 and pedprobr 1.1.0 for faster likelihoods and better handling of looped pedigrees. Much of the remaining work is unglamorous casework ergonomics, replacing stray Norwegian text in Excel output, controlling table heights, fixing karyogram colours.

◆ Prediction

With the map externalised and custom maps loading from multiple formats, the likeliest next step is broader marker-panel coverage through norSTR rather than changes in KLINK itself. Method gains should continue to arrive as pedprobr and pedmut version bumps.

0.0

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.
