How can I parse the file without missing any information? My goal is to mapping the UniProtKB Accession with the nucleotide sequences.
I tried to use the SeqIO in Biopython to parse this file. My goal is to mapping the UniProtKB Accession with the nucleotide sequences, my code:
# Bio.__version__ = '1.79'
from Bio import SeqIO
cds_file = open("/data3/jsun/spgen/ena_data/CON_PRO_1.cds", 'r')
for record in SeqIO.parse(cds_file, "gb"):
print(record.id)
break
However, the db_xref information of CDS is missing in record.features. Is there any way I can get this information using the SeqIO parser? Thanks.
