Graphs are tracks showing scores or other numeric values as a function of genomic position. Graphs are generally displayed as some form of plot (line plot, bar plot, heat map, etc.). The results from tiling arrays are generally represented as graphs. There are two types of graph data: point-based graphs, in which numerical values are associated with individual (single) base positions; and interval graphs, which capture values associated with ranges of genomic positions. IGB can generate certain types of graphs from annotation tracks, based on the data within the annotation track. Read Working With with Graph Tracks
Sequences are sets of DNA residues comprising a chromosome. Sequences can be fully or partially loaded from local files, QuickLoad sites, or DAS servers. It is recommended to load sequence data only for small regions of the genome at a time. IGB allows you to examine sequence data in a separate window called the Sequence Viewer.
