Geneious Prime can convert nucleotide sequences into primers. This is necessary for sequences to show up in the oligo database. To do this, select your sequences and choose Primers → Convert to Oligo from the popup menu that appears. Convert to Oligo can only be performed on sequences less than 400 bp long, and full characteristics (such as primer dimer and hairpin Tms) can only be calculated for primers 60bp or less.
