Sample attributes

Attributes can be associated with tracks and used for filtering, sorting, and grouping data. By default all tracks have at least 3 attributes: Data File, Data Type, and Name. To display additional attributes, load a sample attribute file. IGV displays attribute names and values in the attributes panel between the name panel and the data panel.

Color-coded attribute values#

IGV uses color-coded blocks to represent the attribute values. If two samples have the same color block for a particular attribute, both samples have the same value for that attribute. However, the colors are arbitrary and different sessions of IGV may not use the same colors.
