Hi Roberta,

Yo can make a DAG from your annotation data within the software Blast2GO. You simply need to upload your annotation file into the application. Create a taba separated file with  2 columns, put your sequence names in the first column and the GO annotations in the second (exactly as you showed in your example). Save it as .txt and change the extension to .annot. Use then the import annotation function in Blast2GO. You can use then all functions available in the application.

Hope this helps

To do this I downloaded it's closest relatives from Integr8, blasted the unpublished sequence against each of them and made an assignment based on sequence similarity. Mainly I wanted to do this to compare the unknown sequence to it's closest neighbours. I used a MySQL database to complete the assignments.
