Hey everyone,

I have a weird problem. I am trying to download a number of assemblies from Genbank using Entrez.eftech. Here is my code:

from Bio import Entrez, SeqIO
import csv, sys, os, time, shutil
import httplib, urllib2

Entrez.email="mymail@gmail.com"

def download_genomes():

    #Search for all bacterial assemblies in the assembly database and get their ids
    search_term= "bacteria[orgn] AND all[filter]"
    handle=Entrez.esearch(db="assembly", retmax=500000, term=search_term)
    genome_id=Entrez.read(handle)['IdList']
    print "Fetched Id list..."

    for id in genome_id:

        while True:
            try:
                #Fetch the enrty corresponding to the id
                record=Entrez.efetch(db='assembly', id=id, rettype='fasta', retmode='text')
                time.sleep(3)
                seq_record=Entrez.efetch(db='assembly', id=id, rettype='gbwithparts', retmode='text')
                seq_meta=SeqIO.read(seq_record, "genbank")
                .            
                .  
                .
                #Skipped rest of the code which writes downloaded files to spec. dirs and so on

However, when running this, get a HTTP Error 400: Bad request for every id. When trying out the ids manually in Genbank, the entry is found. Does somebody know what could be going on here? I would appreciate the help!

Cheers!
