gcube vs tEDM
A side-by-side editorial comparison of gcube and tEDM — release velocity, themes, recent moves, and the top alternatives to consider.
gcube vs tEDM: at a glance
What is gcube?
gcube's recent releases are all packaging metadata, not simulation code
gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.
What is tEDM?
The temporal half of the stscl EDM pair, tracking its spatial sibling
tEDM applies empirical dynamic modeling to time series — cross mapping, convergent cross mapping and the logistic map — as the temporal counterpart to spEDM, with which it shares a maintainer and a C++ core. The recent releases are consolidation rather than expansion: index handling in cross mapping corrected, generics taught to accept varying E, k and tau, and the associated paper now cited in the README. Only three releases are visible in the feed.

◆ Current state
gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.
◆ Where it's heading
The February 2026 cluster reads as a package wiring up its archival identity rather than developing: four releases in four days, one of them explicitly a test of the GitHub release path. That is characteristic of research software preparing to be cited — a Zenodo DOI, correct funder attribution and a checklist-compliant description are the deliverables when the funder requires them. Substantive work on mapping functions and grid designation appears earlier and only through tutorial fixes.
◆ Prediction
With the Zenodo integration and metadata now settled, expect attention to return to the simulation functions themselves, most likely driven by what the sibling indicator packages need to test against.
tEDM
0.0ANALYTICS
The temporal half of the stscl EDM pair, tracking its spatial sibling
◆ Current state
tEDM applies empirical dynamic modeling to time series — cross mapping, convergent cross mapping and the logistic map — as the temporal counterpart to spEDM, with which it shares a maintainer and a C++ core. The recent releases are consolidation rather than expansion: index handling in cross mapping corrected, generics taught to accept varying E, k and tau, and the associated paper now cited in the README. Only three releases are visible in the feed.
◆ Where it's heading
tEDM moves in lockstep with spEDM. Configurable distance metrics, varying E/k/tau inputs, strict floating-point comparison and the S3 plotting font unification all appear in both packages within days or weeks, as does the maintainer surname correction. The recent balance has tilted toward correcting library and prediction index handling — the kind of repeated attention that suggests the indexing model was the weak point of the shared core.
◆ Prediction
Expect tEDM to keep inheriting the shared-core changes spEDM lands, with its own releases staying small and centred on cross-mapping parameter handling rather than new method surface.
