What is aniread?

aniread stops asking you to know which tracker wrote the file

aniread is the reader package of the animovement suite, importing output from pose-estimation, centroid and behavioural-scoring tools into aniframe objects. Through 0.5.x the work was per-reader: get_supported_sources() exposed the format list programmatically, read_boris() added behavioural events, and Octron and BORIS each got targeted fixes. 0.6.0 changes the shape of the interface itself — read_dataset() takes any supported file through one entry point and detect_source() works out which software wrote it by inspecting contents, not just the suffix.

What is n1qn1c?

A Fortran-descended optimizer got thread-safe, then found two flags that never worked.

n1qn1c is a quasi-Newton optimization routine translated from Fortran to C, used as a solver backend by the nlmixr2 modeling stack rather than called directly by most users. Its two 2026 releases are a concentrated safety pass: global state converted to thread_local, static removed from local variables in the translated code, integer overflow guards added, and memory leaks closed in the R callback wrappers — plus the gcc-asan and valgrind fixes CRAN asked for.

◆ Current state

aniread is the reader package of the animovement suite, importing output from pose-estimation, centroid and behavioural-scoring tools into aniframe objects. Through 0.5.x the work was per-reader: get_supported_sources() exposed the format list programmatically, read_boris() added behavioural events, and Octron and BORIS each got targeted fixes. 0.6.0 changes the shape of the interface itself — read_dataset() takes any supported file through one entry point and detect_source() works out which software wrote it by inspecting contents, not just the suffix.

◆ Where it's heading

The package is moving from a set of named readers to a dispatcher with the readers behind it, and the hard part is being handled rather than hidden: twelve sources emit .csv, so detection narrows by suffix then inspects content, and DeepLabCut and LightningPose files are structurally identical so it returns the combined 'deeplabcut/lightningpose' rather than guessing wrong. The honesty extends to gaps — optional-dependency detectors are skipped when the package is absent and the error names what was skipped, and SLEAP's csv suffix was withdrawn because auto-detection would have routed files into a reader that cannot read them. Alongside this, read_trackball() was substantially repaired for real two-sensor Bonsai captures, where alignment, clocks, corrupt rows and gap filling were each independently wrong.

◆ Prediction

Expect the withdrawn SLEAP csv suffix to return once read_sleap() gains support, since the changelog explicitly parks it against issue #87. Further detectors are the natural next increment, and the sensor-local-clock warning class suggests trackball alignment is not finished.

A Fortran-descended optimizer got thread-safe, then found two flags that never worked.

◆ Current state

n1qn1c is a quasi-Newton optimization routine translated from Fortran to C, used as a solver backend by the nlmixr2 modeling stack rather than called directly by most users. Its two 2026 releases are a concentrated safety pass: global state converted to thread_local, static removed from local variables in the translated code, integer overflow guards added, and memory leaks closed in the R callback wrappers — plus the gcc-asan and valgrind fixes CRAN asked for.

◆ Where it's heading

The package is being hardened for use inside a parallel modeling framework rather than extended. The audit that produced the thread-safety work also surfaced two plain bugs in features users would have assumed worked: restart = TRUE left the mode at 2 instead of 3 because of a typo, and assign = TRUE referenced the wrong field name so the compressed Hessian was never written to the supplied environment. Earlier work points the same direction — the 6.0.1-12 function-pointer interface exists so nlmixr2est does not need resubmission when this package changes.

◆ Prediction

Expect further memory-safety and sanitizer work rather than algorithmic change; a Fortran-translated numerical core under CRAN's checking regime generates that kind of release indefinitely.
