Expression Profile Descriptions

Expression Profiles provide great flexibility for modeling different kinds of measurement expressions. This page describes the types available in the software. See Expression Profile Distribution Types for related information about types of distributions.

Constant

This profile has two Control Points that are linked to the same intensity.
It is used to select events for a cell type.

Step Up

The Step Up profile has four Control Points. The first two points are linked to have the same intensity values. The last two points are also linked, and are forced to have a higher intensity than the first two.
It is used for measurements that are up-regulated in the cell type.

Step Down

The Step Up profile has four Control Points. The first two points are linked to have the same intensity values. The last two points are also linked, and are forced to have a lower intensity than the first two.
It is used for measurement that are down-regulated in the cell type.

Three Levels

This profile defines three levels of intensity. For each level, there are two Control Points that are linked to the same intensity for the parameter. Each of the levels has no dependencies on the other levels. In other words, the next level can be higher, lower, or even the same intensity as its neighboring level.

N-Levels

This profile has a user-defined number of levels. Each level has two Control Points, one that defines the beginning of the level, and one that defines the end.
