Add sequence number to fasta headers : Hi I have a set of fasta sequences starting with a different header. I need to add sequence number with increasing count (Seq1, Seq2, Seqn...) for each sequence header. Here is the first one:

input:

    >[organism=Fowl Adenovirus] Fowl Adenovirus FAdV hexon gene, isolate FAdV/SP/1184/2013

output:

    >Seq1 [organism=Fowl Adenovirus] Fowl Adenovirus FAdV hexon gene, isolate FAdV/SP/1184/2013
