# Resemblance calculation

Resemblance is the general term in PRIMER used to cover (dis)similarity or distance coefficients. The next stage in both the Fal nematode and environment runs of the **Basic multivariate analysis** wizard was to create an appropriate triangular resemblance matrix between all pairs of samples. This is a run of **Analyse>Resemblance** on the pre-treated (transformed or normalised) worksheet. Relevant defaults will be suggested, given the Data type, i.e. (Measure•Bray-Curtis) for biota and (Measure•Euclidean distance) for environmental variables, and (Analyse between•Samples) in both cases. There are, however, nearly 50 other possible choices on this dialog, see Section [5](https://learninghub.primer-e.com/books/primer-v7-user-manual-tutorial/chapter/5-resemblance-similarities-dissimilarities-and-distances).
