Downloading Cds Fasta Sequences From Gene Ids

Question

[lin.barnum]

I have a list of geneIDs obtained from UCSC genome browser like this:

CG6854
CG8119
CG8359
CG9437
CpipJ_CPIJ001450
CpipJ_CPIJ002577
CpipJ_CPIJ011605
CpipJ_CPIJ011632
CpipJ_CPIJ016978
GA11162
GA11800
GA12610

All of these are from the insect group. I would like to obtain the fasta CDS for these genes without introns. I can do this individually so hopefully there should a way to automate it as I have 195 of these. Any ideas on how this can be done would be appreciated.

If you want to automate it install Python and Biopython

open python

from Bio import Entrez , SeqIO
handle = Entrez.efetch("pubmed", id="CG6854,CG8119,CG8359,CG9437,CpipJ_CPIJ001450", retmode="xml")
records = Entrez.parse(handle)
for record in records:
      write_list.append(record)

SeqIO.write(write_list, "output_file","fasta")

in place of id copy paste all ids. and you will get a output file.
