This page assumes you are familiar with making 2 subgroups. If you are not, please see 'How do I make subgroups'.
To make more than 2 sample subgroups, enter multiple search terms, such as 'C:>15' into the search box. Separate each search term with a ';'.
This can be used for a number of situations:
To divide a single numerical column into more than 2 subgroups (e.g. geneA high, geneA mid, and geneA low)
To make subgroups over the expression of two genes such that you get 4 subgroups (e.g. geneA high + geneB high, geneA low + geneB high, geneA high + geneB low, geneA low + geneB low)
To make subgroups over the expression of a gene and a categorical column (e.g. geneA high + Estrogen Receptor positive, geneA low + Estrogen Receptor positive, geneA high + Estrogen Receptor negative, geneA low + Estrogen Receptor negative)
To make subgroups over two categorical columns (e.g. Estrogen Receptor positive + HER2 positive, Estrogen Receptor negative + HER2 positive, Estrogen Receptor positive + HER2 negative, Estrogen Receptor negative + HER2 negative)
See below for an example of each.
In the screenshot below you can see that column D that ranges from 7.3 to 12. If you wanted to have 3 groups: 7.3 - 9, 9 - 10, and 10 - 12, you would enter:
C:>9 ; C:>10
into the search bar and then choose 'New subgroup column' from the filter/subgroup drop down menu.

In the screenshot below you can see that column E (ERBB2 gene expression) that ranges from 10 to 16. If you wanted to have 4 groups: ERBB2 > 13 + Estrogen Receptor positive, ERBB2 <= 13 + Estrogen Receptor positive, ERBB2 > 13 + Estrogen Receptor negative, ERBB2 <= 13 + Estrogen Receptor negative), you would enter:
E:>13 ; C:Negative
into the search bar and then choose 'New subgroup column' from the filter/subgroup drop down menu.
In the screenshot below, if you wanted to have 4 groups: Estrogen Receptor positive + HER2 positive, Estrogen Receptor negative + HER2 positive, Estrogen Receptor positive + HER2 negative, Estrogen Receptor negative + HER2 negative you would enter:
C:Negative ; D:Negative
into the search bar and then choose 'New subgroup column' from the filter/subgroup drop down menu.
