We really want to be able to have certain samples marked as ungrouped, such that when we look at the LDA - the LDA doesn't try to attribute any samples to the 'ungrounded' category.\r\n\r\n#### Very simple example\r\nThree taxa (or taxa groups selected): *TBOE*, *TMON* and *TBOE-MONO*\r\n**Currently** - the LDA will specify for each sample which of these **three** groups they are best fitted within.\r\n**Desire** - *TBOE-MONO* is marked as ungrouped such that the LDA will try to fit each sample into either *TBOE* or *TMON* (but no sample can be classified as *TBOE-MONO*).\r\n\r\n--\r\n\r\n###### A generic solution would be most welcome"}}
