I need to get SNP data from HapMap via biomaRt, but am having trouble getting any results from any query of the hapmap_rel27 dataset. For example, both of the following: HM <- useMart("HapMap_rel27","hm27_variation_ceu") ceu <- getBM( c("chrom","start","strand","marker1"), filters=c("chrom"), values="chr22",HM) ) hapmap <- useMart("HapMap_rel27", dataset="hm27_variation_yri") yri <- getBM(c("chrom","start","alleles","ref_allele","ref_allele_freq","othe r_allele_freq",filters=c("chrom","coding_nonsynon"),values=list("chr19 ",TRUE),mart=hapmap) result in an empty table such as: > head(yri) [1] chrom start alleles ref_allele ref_allele_freq other_allele_freq <0 rows> (or 0-length row.names) I've tried with both biomaRt 2.8.1 and 2.9.2. Queries to marts ensembl or snp work as expected. Am I missing a detail in my queries to HapMap, or is there an issue with the mart?

Hi Deidre, It looks like there is some issue with HapMap in the BioMart central repository. You might want to do your query using the hapmap web interface at: http://hapmap.ncbi.nlm.nih.gov/biomart/martview/ Cheers, Steffen On Fri, Jul 22, 2011 at 5:58 AM, Deidre <deidre.krupp at="" duke.edu=""> wrote: > I need to get SNP data from HapMap via biomaRt, but am having trouble > getting any results from any query of the hapmap_rel27 dataset. ?For > example, both of the following: > > HM <- useMart("HapMap_rel27","hm27_variation_ceu") > ceu <- getBM( > c("chrom","start","strand","marker1"), > filters=c("chrom"), values="chr22",HM) > ) > > hapmap <- useMart("HapMap_rel27", dataset="hm27_variation_yri") > yri <- > getBM(c("chrom","start","alleles","ref_allele","ref_allele_freq","ot her_allele_freq",filters=c("chrom","coding_nonsynon"),values=list("chr 19",TRUE),mart=hapmap) > > result in an empty table such as: > > ?> head(yri) > [1] chrom ? ? ? ? ? ? start ? ? ? ? ? ? alleles > ref_allele ? ? ? ?ref_allele_freq ? other_allele_freq > <0 rows> (or 0-length row.names) > > I've tried with both biomaRt 2.8.1 and 2.9.2. ?Queries to marts ensembl > or snp work as expected. ?Am I missing a detail in my queries to HapMap, > or is there an issue with the mart? > > Regards, > Deidre > > > ?> sessionInfo() > R version 2.13.0 (2011-04-13) > Platform: i386-pc-mingw32/i386 (32-bit) > > locale: > [1] LC_COLLATE=English_United States.1251 ?LC_CTYPE=English_United > States.1252 ? ?LC_MONETARY=English_united States.1252 > [4] LC_NUMERIC=C ? ? ? ? ? ? ? ? ? ? ? ? ?
