Hi,

I have a set of data with chromosome number and coordinates of the sequences
such as,chr10, start 1000, end 2000.
I have tried using biomart to retrieve the genomic sequences for my dataset,
but I didn't get success, I used seqType argument as:
seqType="genomic", it reported error as"The type of sequence specified with
seqType is not available. Please select from: cdna, peptide, 3utr, 5utr",
but I have seen this "genomic" argument for seqType in the help file. So
what's going on there?

Or anyone can recommend a package which can help me retrieve the genomic
sequences from hg18 with known chromosome number and sequences
coordinates(start and end).

Thanks.
