glyparse vs pedbuildr: at a glance
What is glyparse?
glyparse is quietly becoming the universal reader for glycan text notation.
glyparse converts the various text encodings of glycan structures into glyrepr objects. Version 0.7.0 was the widest release in the window, adding parsers for GlyCAM IUPAC, IUPAC-compact, KCF, and LINUCS and teaching auto_parse() to route them, alongside a long list of GlycoCT and WURCS edge cases. The rest of the window is error-handling and performance work: an on_failure switch, a 10-30x speedup on large inputs, and NA and name preservation.
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.

glyparse is quietly becoming the universal reader for glycan text notation.
◆ Current state
glyparse converts the various text encodings of glycan structures into glyrepr objects. Version 0.7.0 was the widest release in the window, adding parsers for GlyCAM IUPAC, IUPAC-compact, KCF, and LINUCS and teaching auto_parse() to route them, alongside a long list of GlycoCT and WURCS edge cases. The rest of the window is error-handling and performance work: an on_failure switch, a 10-30x speedup on large inputs, and NA and name preservation.
◆ Where it's heading
Two things are being built at once. Coverage keeps widening, both in the number of notations supported and in how much malformed or ambiguous real-world input each parser tolerates: alditol residues, unknown ring positions, ambiguous sialic acid descriptors, uppercase residue IDs. Meanwhile the package is hardening for batch use, with progress bars, vectorized speed, and a choice between erroring and returning NA on unparsable strings.
◆ Prediction
With the major notations now covered, expect further releases to go to robustness on messy inputs and to keeping pace with glyrepr's structure representation rather than adding formats.
pedbuildr
0.0ANALYTICS
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 glyparse and pedbuildr?
Both compete on the same themes — performance, r packages — within Analytics. glyparse 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 glyparse better than pedbuildr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. glyparse and pedbuildr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
