Advanced GBK Editor tool
You use the Advanced GBK Editor tool to view, edit or annotate a GenBank reference file. You can load a .gbk/.txt file which is a file that contains both the annotations and the sequence or you can load the files separately. A .gbs file contains only the annotations (no sequences) and the .fna file contains only the sequence (no annotations). To load the GenBank file that is to be edited/annotated, do one of the following:
• On the GBK Editor window main menu, click File > Open.
• On the GBK Editor window toolbar, click the Load icon
