Here is an example bed file, made by taking segments from the A_thaliana_Jun_2009 gene annotations and replacing the chromosome names: exBed.bed

As per the directions in Personal Synonyms, add this chromosome.txt file as a chromosome synonyms file. Restart IGB.
Start IGB and choose the A_thaliana_Jun_2009 genome. Load the exBed.bed file. Use the "genome" load mode, the file only includes a scattering of annotations.
- Observe that the annotations from exBed appear on the same chromosomes as the automatically loaded annotations.
If IGB creates new chromosomes labeled "KlingonChr1" etc, then the link between chromosome "KlingonChr5" and "Chr5" is not functioning.
