01One seed lotA guided walk from your germination counts to a fitted decay curve — every knob (σ, Ki, P-values) explained inline as you go.Guided fit →02A whole collectionFormal protocol-specific longevity models: taxon × accession × storage × germination protocol, fit on actual counts, with paired 5 °C / −18 °C shared-Ki comparisons, plots, and ZIP downloads.Batch fit →03Long-term monitoring dataThe recollection-interval management analysis: baselines, observed intervals (overall and at recommended storage, kept separate), freeze flags, accession plots, and downloadable results.RCI pipeline →04Competing decay modelsFit four published seed-longevity models to the same counts, ranked by AICc with a plain-language verdict — then save, share, and publish the result.Model workbench →
Not sure which fits? A single germination time series is 01. A spreadsheet with taxon/accession columns is 02. A monitoring export with storage codes (Initial / −18C / 5C / Ambient) is 03. If you want to ask which curve shape your data actually supports, that's 04.
Prefer to run the analysis on your own machine? Every component here is also a standalone script (Python and R) — same science, cross-validated against this site's engine, no upload required.
