Accession numbers list to functional/taxonomic list?

[ereyred]

Hello, I have DP_GP_cluster outputs. I'm specifically looking at the optimal_clustering.txt file, which gives me the cluster name and a list of all the gene accession IDs in that cluster. How do I convert these gene IDs into information I can use, ie functional or taxonomic info on the genes in each cluster? Eg this cluster has mostly this function group, etc? Is there a way to export the cluster info and blast it or run it on a programme like Megan to look at the cluster profiles? I can look up each ID individually on NCBI but obviously that's not useful for long lists. Thanks so much! Any help from anyone will be much appreciated.
