The Current Genome panel contains Species and Genome Version (red box), which used to be part of the Data Access panel in IGB versions 6.6 and 6.5. The whole panel used to be in the Data Access panel in even older versions of IGB. To improve ease of use, it was moved to a side tray position so that it could display more sequences; while species with assembled genomes have a lower number of whole chromosomes, some genomes only exist as contigs, and these genomes have tens, hundreds or thousands of assemblies that need to be displayed. We have found that the portrait display of these sequences allows users to more readily find particular sequences. You can set the Current Genome panel to appear in either the left or right tray.
The sequences that are displayed in this tab can be sorted by name or by size. Clicking the column header Sequence(s) will sort by sequence name in alphabetical order. Clicking on Length will sort the sequences by size. An additional piece of information is the number next to Sequence(s), which indicates how many sequences are present in the genome version.
Most genome versions will have the option of being displayed as 'genome'. This option is found at the bottom of the Sequence(s) list, if it is available. Using this option displays every annotation in a linear arrangement, leaving a space between each chromosome/ contig (red arrows). In the coordinate axis, IGB will show you the relative length of each chromosome as black bars, with white space in between (red box). To display the entire genome, all of the data must be loaded. For organisms that have an autoloaded reference sequence, such as human, mouse, Drosophila, Arabidopsis, etc., you can select genome immediately (picture below shows the whole genome displayed for Arabidopsis). For other organisms, you will need to load each chromosome or contig individually.
