# Selecting by number and non-missing

It may sometimes be easier to use the sample numbers, here **Select>Samples**>•Sample numbers> <ins>1,2,5,6,11,12,15,16</ins>, though this is more likely to be useful where such numerical lists are output in results (e.g. by the BEST routine, Section [13](https://learninghub.primer-e.com/books/primer-v7-user-manual-tutorial/chapter/13-linking-assemblage-to-environment-best-bio-env-linktree)), and can be copied and pasted into this dialog box.

The final possibility is **Select>Samples**>(•No missing values) in which only those samples which have no entries of <code style ="color : green">Missing!</code> for any of their variables will be selected. <code style ="color : green">Missing!</code> entries are unlikely for species matrices (as here) but this facility might be useful sometimes for environmental arrays,  to find samples which have a complete set of variables.
