Canoco 5.15 is now available for distribution! We are actively filling orders for Canoco 5.15  on a first-come first served basis. If you want Canoco 5.15 as soon as possible, place your order now.

Version 5.15 brings multiple improvements.

The most important change is the new, alternative method of performing Monte  Carlo permutation tests: instead of permuting rows of response data  (residualized with respect to covariates, for partial constrained ordinations), users can choose to permute rows of predictor table (residualized with respect to covariates in partial constrained ordinations).

Differences between permuting predictors vs. response data are discussed in two research papers present in the "pdf" sub-folder of the Canoco 5 installation folder.

one published -  RDA_permutations.pdf

one manuscript CCA_permutations_draft.pdf

Functionality offered for dc-CA and dc-PCA analysis templates was  further extended, with new graph types and an extended description  of analysis results.

You will find further details in the Canoco 5.15 section of the Canoco Overview.

Canoco in Microbiome Studies!

Originally developed for use in the study of Forest and Meadow Communities, applications of Canoco have broadened to encompass the study of microbiomes.

Taxonomic Levels

Provides a novel way to deal with the various taxonomic levels by juxta-positioning the tables to form one big table with as many columns (one for each taxon at each level).
