[BioC] Create consensus fasta file from indexed Bam file

[Jacques LE GOUIS [guest]]

Hello,
I have an indexed bam files from 454 sequencing on short reference sequences. I would like to create a consensus sequence in fasta format from this bam file using R Bioconductor. Is there a way to do that simply ?
Thanks in advance
Jacques
