Linking to GEvo

It's very easy to link into GEvo, which lets you build URLs that specify sequences to be pulled from CoGe's database or from NCBI using an accession. [PlantGDB] has done this for [maize bacs] and an example link deconstructed is:

http://synteny.cnr.berkeley.edu/CoGe/GEvo.pl?accn1=Os02g51290;dr1up=50000;dr1down=50000;accn2=Sb04g027950;dr2up=50000;dr2down=50000;gbaccn3=AC190647;num_seqs=3;

(X) refers to the sequence number where the first sequence is 1, the second is 2, the third is 3, etc.

accn(X): retrieve sequence from CoGe's database using an accession. dr(X)up: the amount of sequence to the left of the accession (in base pairs) dr(X)down: the amount of sequence to the right of the accession (in base pairs)

gbaccn(X): the genbank accession to retrieve a sequence from NCBI.

num_seqs=(Y): the number of sequences being submitted

So, the above links specifies three sequences: Seq1: database retrieval on name Os02g51290 with 50,000bp to the left and right Seq2: database retrieval on name Sb04g027950 with 50,000bp to the left and right Seq3: NCBI retrieval for accession AC190647
