glydb vs KLINK
A side-by-side editorial comparison of glydb and KLINK — release velocity, themes, recent moves, and the top alternatives to consider.
glydb vs KLINK: at a glance
What is glydb?
glydb is pulling GlyGen's structure database onto the user's own disk.
glydb bundles glycan structure reference data and provides lookup helpers for compositions, structures, and species. The 0.6.0 release grew the bundled dataset to 19,436 GlyGen structures including non-intact glycans, and changed glytoucan_to_struc() to search that local data before falling back to the online GlyGen API. Version 0.4.0 added a confidence attribute that glyanno uses to rank candidate matches.
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.

glydb
0.0ANALYTICS
glydb is pulling GlyGen's structure database onto the user's own disk.
◆ Current state
glydb bundles glycan structure reference data and provides lookup helpers for compositions, structures, and species. The 0.6.0 release grew the bundled dataset to 19,436 GlyGen structures including non-intact glycans, and changed glytoucan_to_struc() to search that local data before falling back to the online GlyGen API. Version 0.4.0 added a confidence attribute that glyanno uses to rank candidate matches.
◆ Where it's heading
The arc is from thin wrapper toward self-contained reference: the bundled data keeps growing, online lookups are demoted to fallbacks, and classification vocabularies are being adopted from GlyGen rather than invented locally. The other constant is chasing glyrepr, whose structure representation has changed enough times that regenerating the bundled indexes is a recurring release note.
◆ Prediction
Expect the bundled dataset to track further GlyGen and GlyTouCan releases, with the online API path continuing to narrow to accessions the local data does not cover.
KLINK
2.5ANALYTICS
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.
