glyexp vs ibdsim2
A side-by-side editorial comparison of glyexp and ibdsim2 — release velocity, themes, recent moves, and the top alternatives to consider.
glyexp vs ibdsim2: at a glance
What is glyexp?
glyexp is retiring its own data container and handing the job to Bioconductor.
glyexp is the container layer under the glycoverse stack, and it just changed what that container is. Versions 0.15.0 and 0.16.0 introduced GlycomicSE and GlycoproteomicSE as SummarizedExperiment subclasses, taught the dplyr-style verbs to operate on them, and then deprecated the legacy experiment() constructor and its accessors. Earlier releases in the window were narrower: as_pseudo_glycome(), a magrittr-free rewrite, and an offline standardize_variable().
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.

glyexp

glyexp is retiring its own data container and handing the job to Bioconductor.
◆ Current state
glyexp is the container layer under the glycoverse stack, and it just changed what that container is. Versions 0.15.0 and 0.16.0 introduced GlycomicSE and GlycoproteomicSE as SummarizedExperiment subclasses, taught the dplyr-style verbs to operate on them, and then deprecated the legacy experiment() constructor and its accessors. Earlier releases in the window were narrower: as_pseudo_glycome(), a magrittr-free rewrite, and an offline standardize_variable().
◆ Where it's heading
The package is moving from a bespoke object model to the Bioconductor one, and doing it in explicitly numbered stages tracked in a single issue (glyexp#15). Stage I added the subclasses as experimental; Stage II deprecated the old container and pushed the migration through ten sibling packages within days. The tidy manipulation verbs are being kept as the compatibility bridge, which suggests the dplyr surface is what the maintainer considers glyexp's actual contribution once the container is someone else's.
◆ Prediction
Expect a Stage III release that removes the deprecated experiment() constructor and accessors outright, leaving GlycomicSE and GlycoproteomicSE as the only supported containers.
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.
