[BioC] how to get pig genome and for miRNA target scan

[wang peter]

dear sean：

The 3' UTR data can be retrieved
but some are missing, i donot know why

dataset1 <-useDataset(dataset="sscrofa_gene_ensembl",mart=mart)
attributes <- listAttributes(dataset1)
seq = getSequence(chromosome=1,start=1, end=50000,
type="ensembl_gene_id", seqType="3utr", mart = dataset1)



"3utr"	"ensembl_gene_id"
"1"	"Sequence unavailable"	"ENSSSCG00000004013"
"2"	"Sequence unavailable"	"ENSSSCG00000004017"
"3"	"CTTGTTCCACGTACCAAAGAGTGCTTGCTTCTCACCTTTTCAGAAACACACGCCATTATATTATAGAGTTGGAAACATCACA"	"ENSSSCG00000004009"
