glyclean vs ibdsim2
A side-by-side editorial comparison of glyclean and ibdsim2 — release velocity, themes, recent moves, and the top alternatives to consider.
glyclean vs ibdsim2: at a glance
What is glyclean?
glyclean stopped trusting QC samples to choose its preprocessing strategy.
glyclean handles preprocessing and QC for glycomics and glycoproteomics data: filtering, imputation, normalization, batch correction, and compositional transforms. The defining change in this window is 0.14.0, which abandoned QC coefficient-of-variation heuristics for choosing imputation and normalization methods in favor of rules keyed to sample size. The 0.15.x releases then finished removing the deprecated QC arguments and moved the whole package onto glyexp's SummarizedExperiment containers.
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.

glyclean stopped trusting QC samples to choose its preprocessing strategy.
◆ Current state
glyclean handles preprocessing and QC for glycomics and glycoproteomics data: filtering, imputation, normalization, batch correction, and compositional transforms. The defining change in this window is 0.14.0, which abandoned QC coefficient-of-variation heuristics for choosing imputation and normalization methods in favor of rules keyed to sample size. The 0.15.x releases then finished removing the deprecated QC arguments and moved the whole package onto glyexp's SummarizedExperiment containers.
◆ Where it's heading
Two commitments are visible. First, defaults should be defensible rather than adaptive: the maintainer explicitly judged CV-in-QC-samples not robust and replaced it with sample-size thresholds. Second, the package wants containers, not matrices, and 0.15.0 makes bare matrix inputs an error. Dependency pruning runs alongside both, with imputeLCMD reimplemented away so auto_clean() works out of the box.
◆ Prediction
The compositional data thread is the least finished part of the package, so further CoDA methods or a broader auto_coda() are the likeliest next additions.
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.
