What is ltertools?

A column-key toolkit for stitching decades of ecological field data into one table.

ltertools serves the Long Term Ecological Research network, where the same measurement carries a different column name at every site and in every era. Its core is a column key: begin_key drafts one, harmonize applies it, and the 2.0.0 release added check_key to validate a key and standardize to apply one to a single dataset. Harmonization of files above 5 MB now runs in roughly half the time.

What is phyloatlas?

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

A column-key toolkit for stitching decades of ecological field data into one table.

◆ Current state

ltertools serves the Long Term Ecological Research network, where the same measurement carries a different column name at every site and in every era. Its core is a column key: begin_key drafts one, harmonize applies it, and the 2.0.0 release added check_key to validate a key and standardize to apply one to a single dataset. Harmonization of files above 5 MB now runs in roughly half the time.

◆ Where it's heading

Development has moved from breadth to depth. The first year added assorted utilities — temperature conversion, solar day length, a site timeline — while the last two releases have concentrated on the key workflow itself: incremental key expansion, validation, per-dataset application, and speed. A dependency archival forced the removal of the JSON helper, trimming the package back toward that core.

◆ Prediction

The key workflow now has draft, expand, check and apply steps, so the remaining gap is diagnostics on the harmonized output; the entries show no other thread in progress.

An atlas of the tree of life that keeps publishing what it got wrong, and stopped shipping the trees it does not own.

◆ Current state

This is a curated deposit of species-level phylogenies — 264 trees across 62 partitions, 247 of them time-calibrated — paired with a species-name dictionary of roughly 638,000 standardized labels and per-tree provenance. It is moving through peer review at Methods in Ecology and Evolution, and the release stream is essentially a public erratum log: eight releases in five weeks, each reconciling the deposit against source papers, the manuscript, and its own metadata. The most recent replaced the turtle canonical with a 274-tip ultrametric chronogram after the previous tree failed time-calibration integrity checks.

◆ Where it's heading

The project's defining decision is that it archives the recipe rather than the corpus. Since 1.0.3 the Zenodo deposit holds metadata, provenance, and standardization code while the tree files live at their original sources, and the same principle was applied again when the TimeTree-of-Life was removed at the TimeTree project's request and reduced to a citation. What makes the correction log unusual is its direction: partitions keep getting reclassified from dated to undated as verification confirms the source papers described chronograms they never deposited. The atlas is being built to be honest about archival uncertainty rather than to maximize coverage.

◆ Prediction

The release cadence is driven by the manuscript review cycle, so expect corrections to continue until MEE acceptance and then slow sharply; the open thread most likely to produce the next one is the remaining recoverable archival uncertainty flagged across non-Condamine dated source trees.
