glysmith vs ibdsim2: at a glance
What is glysmith?
glysmith turns an LLM interview into a reproducible glycomics analysis pipeline.
glysmith is the orchestration layer of glycoverse: inquire_blueprint() interviews the user, and forge_analysis() runs the resulting step blueprint end to end. The recent 0.12.x releases wired that pipeline onto glyexp's new SummarizedExperiment containers, and 0.12.0 pulled QC sample handling out of step_preprocess() entirely. The larger feature release was 0.11.0, which added structure inference and three more enrichment steps to the step catalogue.
What is ibdsim2?
A pedigree IBD simulator that absorbed its own web app and now optimises for dense marker panels.
ibdsim2 simulates identity-by-descent sharing along chromosomes for arbitrary pedigrees, in both autosomal and X-chromosomal form, with downstream tools for segment statistics, pattern finding and distribution plots. Since 2.1.0 the Shiny front end lives inside the package and launches via launchApp() rather than sitting in a separate repository. The latest release is performance work, with profileSimIBD() substantially sped up for dense marker panels and ibdsim() skipping recombination in pedigree branches that cannot affect the result.

glysmith turns an LLM interview into a reproducible glycomics analysis pipeline.
◆ Current state
glysmith is the orchestration layer of glycoverse: inquire_blueprint() interviews the user, and forge_analysis() runs the resulting step blueprint end to end. The recent 0.12.x releases wired that pipeline onto glyexp's new SummarizedExperiment containers, and 0.12.0 pulled QC sample handling out of step_preprocess() entirely. The larger feature release was 0.11.0, which added structure inference and three more enrichment steps to the step catalogue.
◆ Where it's heading
The package is growing along two axes: more steps in the catalogue, and less ceremony around getting to them. QC handling and preprocessing arguments keep being removed rather than added, while the AI layer widens to more providers instead of getting more elaborate. glysmith is also the package that absorbs the rest of the stack's reorganizations, routing enrichment to glyfun after glystats deprecated it and pulling structure inference from glyanno.
◆ Prediction
Expect the step catalogue to keep tracking sibling packages, with new steps appearing shortly after the packages behind them ship the underlying capability.
ibdsim2
2.5ANALYTICS
A pedigree IBD simulator that absorbed its own web app and now optimises for dense marker panels.
◆ Current state
ibdsim2 simulates identity-by-descent sharing along chromosomes for arbitrary pedigrees, in both autosomal and X-chromosomal form, with downstream tools for segment statistics, pattern finding and distribution plots. Since 2.1.0 the Shiny front end lives inside the package and launches via launchApp() rather than sitting in a separate repository. The latest release is performance work, with profileSimIBD() substantially sped up for dense marker panels and ibdsim() skipping recombination in pedigree branches that cannot affect the result.
◆ Where it's heading
Two long-running threads. One is the app as a first-class part of the package, which has been getting input validation, dependency checks and plotting fixes release after release, treating a research GUI as software to be maintained rather than a demo. The other is numerical care: the built-in recombination map was rebuilt in 2.3.0 with better chromosome endpoints and a thinning algorithm that cut it from about 38,000 points to 14,000 without losing accuracy, and IBD segment merging has been made consistent across the realised-coefficient functions. The maintainer flags repeatedly that seeded results may differ across versions, which is the right disclosure for a simulator used in published analyses.
◆ Prediction
The recent work points at further speed on dense panels and continued hardening of app input handling, both of which have appeared in each of the last several releases. Nothing here signals a new modelling capability on the way.
