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 pedbuildr?

pedbuildr reconstructs pedigrees from DNA, and it just got much faster at the search.

pedbuildr infers pedigree structure from marker data by scoring candidate pedigrees against likelihoods. Version 0.4.0 moved reconstruct() to mirai for parallel likelihood computation, deprecated the old numCores argument, and picked up the improved loop breaking from pedtools and pedprobr, which lets many complex looped pedigrees succeed where they previously failed. buildPeds() also got significantly faster in its default configuration where mating between lineally related individuals is disallowed.

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.

pedbuildr reconstructs pedigrees from DNA, and it just got much faster at the search.

◆ Current state

pedbuildr infers pedigree structure from marker data by scoring candidate pedigrees against likelihoods. Version 0.4.0 moved reconstruct() to mirai for parallel likelihood computation, deprecated the old numCores argument, and picked up the improved loop breaking from pedtools and pedprobr, which lets many complex looped pedigrees succeed where they previously failed. buildPeds() also got significantly faster in its default configuration where mating between lineally related individuals is disallowed.

◆ Where it's heading

The package is bounded by two costs: how many candidate pedigrees it enumerates and how expensive each likelihood is. The recent release attacks both, parallelizing the likelihoods and speeding up enumeration in the common case. The earlier 0.3.0 release worked on the other end, adding inbreeding limits and a proper result class so the output of a large search is manageable. Releases are infrequent, roughly three years apart in this window.

◆ Prediction

Expect the candidate generation side to receive the same attention the likelihood side just did, since search space size is the remaining bound on what pedbuildr can reconstruct.

Frequently asked questions

What is the difference between glydb and pedbuildr?

Both compete on the same themes — r packages — within Analytics. glydb and pedbuildr 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 glydb better than pedbuildr?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. glydb and pedbuildr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
