I have a number of bed files, for which I would like to extract the corresponding fasta sequences. What is the best way to do this in batch (i.e. without using e.g. the UCSC table browser), since UCSC does not provide (to my knowledge) any web service.. any Bioperl solution ? Or some other web service ? If possible, I would like to avoid installing the genome locally (otherwise the bedtools would be a solution).
