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 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.

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().

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.
