GO Annotation File Example
The file format of a gene association file, along with sample annotations, is shown below. Red text denotes required fields; the rows with column numbers are not part of the file, but are included here for convenience in viewing.
In the annotation files, each annotation (association of a single gene product with a single GO term) takes up one line, so the contents columns 1 through 15 would appear on a single line. They have been split up here for ease of viewing.
