# Accessing other resemblance measures
PRIMER 7 allows the user choice of 44 other resemblances, firstly divided into two (mutually exclusive) types: Similarities (including L&L’s S numbers) or Dissimilarities/Distances (including L&L’s D numbers); then most of the same coefficients split instead into Quantitative or Presence/ Absence measures; and finally two specialised groups of Correlation coefficients and Taxonomic-based P/A measures (the latter using an aggregation file of the type met in Section [2](https://learninghub.primer-e.com/books/primer-v7-user-manual-tutorial/chapter/2-factors-and-indicators-identifying-sample-and-species-groups), on species relatedness). These are all accessed through the Measure•Other button and the drop-down list.
