[galaxy-user] generating a new fasta from a pileup

Hi On a separate issue, I have been having trouble generating a corrected fasta file based on a pileup. I have a dataset that is a resequenced genome and I want to correct the fasta file based on the consensus and then re run the alignments to see how it affects things. However, I cannot for the life of me figure out how to do it in Galaxy. Any help appreciated! David
