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 collectionMany taxa, many accessions, one upload. Every lot fit independently — never pooled — with per-lot curves and honest, explained P-values.Batch fit →03Long-term monitoring dataThe full recollection-interval workflow behind the catalog: baselines, observed intervals, support flags, freeze sensitivity, and a downloadable publication sheet.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.
