Further comments on the NCBI Batch Entrez; unfortunately it does not always
work depending on some error that has not yet been solved. One solution is
using the main page of the NCBI, if you want to retrieve the sequences for many
accession numbers. Just remember to separate the accession numbers by comma and
then follow Joe's instructions for obtaining the sequences.
