I noticed i can't get efetch to retrieve sequence on a reverse strand:

def fasta_from_chords(x): 
    import sys
    sys.path.append('/uge_mnt/home/tim_ivanov/pythonlibs/biopython-1.71')
    from Bio import Entrez, SeqIO
    Entrez.email = "user@email.com" 
    handle = Entrez.efetch(db="nucleotide",id=x[0],seq_start=x[1],seq_stop=x[2],strand=x[3],rettype="fasta")
    record = SeqIO.read(handle, "fasta")
    handle.close()
    return record

this is the function i've made, where x variable contans an array with: accession number, coordinate 1, coordinate 2, strand When i use it, the sequence returns on the straight strand only. Is there a way to fix it?
