  Number of sequences in database:  7,546

 

I can get only top matching sequence so I can give option like below,

blastn -db .DB/ABC_Exon23.fasta.db -query ./test.fasta -out ./test.out -num_descriptions 1 -num_alignments 1-word_size 10

But then results will be

C_08_94                                                               510   7e-145

Actually I want to get below

C_08_02_08                                                            510   7e-145

 

So I want to order by ASC of results and get an top one.

PS. Top one has to be top score , order priory 1. Score 2. Name.

Anyone has good idea?

Thanks!
