kwb.db vs segregatr: at a glance
What is kwb.db?
A water-research lab's ODBC helper, still fighting Windows database drivers a decade in.
kwb.db is internal tooling from Kompetenzzentrum Wasser Berlin that wraps ODBC access to MS Access and similar databases for the lab's R workflows. Its functionality covers schema inspection, relation reading and database dumps, with a long-standing preoccupation with the 32-bit versus 64-bit driver split on Windows. The most recent release pins a newer RODBC to fix Windows installation.
What is segregatr?
A segregation-analysis tool that keeps widening which pedigrees it can actually handle.
segregatr computes full-likelihood Bayes factors for variant segregation in families, built on pedtools and part of the wider pedsuite ecosystem. Its releases are infrequent but each one lifts a structural restriction: loops, recessive and X-linked models, liability classes, and most recently a proband-free variant of the score. The companion shinyseg app gives the same machinery a clinical front end.

kwb.db
0.0ANALYTICS
A water-research lab's ODBC helper, still fighting Windows database drivers a decade in.
◆ Current state
kwb.db is internal tooling from Kompetenzzentrum Wasser Berlin that wraps ODBC access to MS Access and similar databases for the lab's R workflows. Its functionality covers schema inspection, relation reading and database dumps, with a long-standing preoccupation with the 32-bit versus 64-bit driver split on Windows. The most recent release pins a newer RODBC to fix Windows installation.
◆ Where it's heading
The visible history is dominated by driver plumbing rather than features. Early versions added a bridge for calling 32-bit ODBC drivers from a 64-bit R session, then reversed course once 64-bit drivers shipped with MS Office, preferring RODBC directly and falling back only when needed. Later work exposed more of the internals — dumpDatabase, SQL builders, then schema and relation readers — turning a connection helper into something closer to a metadata extractor. The 2025 release is pure survival, and its note candidly records that Ubuntu and macOS installs still fail in CI.
◆ Prediction
Expect the next release to respond to another RODBC or driver breakage rather than to add functionality, given that installation has been the binding problem across the last several releases.
segregatr
0.0ANALYTICS
A segregation-analysis tool that keeps widening which pedigrees it can actually handle.
◆ Current state
segregatr computes full-likelihood Bayes factors for variant segregation in families, built on pedtools and part of the wider pedsuite ecosystem. Its releases are infrequent but each one lifts a structural restriction: loops, recessive and X-linked models, liability classes, and most recently a proband-free variant of the score. The companion shinyseg app gives the same machinery a clinical front end.
◆ Where it's heading
The through-line is coverage of awkward real-world pedigrees rather than new statistics. Loops were handled for the core score in 0.3.0 and then extended to liability classes in 0.4.0, so the same structural capability is being pushed through the codebase feature by feature. The 2025 release moves in a different direction, relaxing the requirement for a designated proband. Development is slow and steady, roughly annual, and tracks its pedtools dependency closely.
◆ Prediction
Expect the next release to continue relaxing modelling constraints — the pattern of retrofitting each new capability across loops, liability classes and inheritance models is unfinished — rather than expanding beyond segregation scoring.
