I am getting the error: "Attributes from multiple attribute pages are not allowed" when trying to use the built-in DAS server of BioMart 0.7.
My local mart is configured similar to Ensembl mart and so the filters and attributes for the importable/exportable pairs ensembl_das_chr and ensembl_das_gene are identical to Ensembl. das_gene request works: myserver/biomart/das/default__hsapiens_gene_ensembl__ensembl_das_gene/features?segment=.... but das_chr request (myserver/biomart/das/default__hsapiens_gene_ensembl__ensembl_das_chr/features?segment=....) doesn't work, and shows this error: "Attributes from multiple attribute pages are not allowed" The attributes listed in the ensembl_das_chr exportable are: ensembl_gene_id,start_position,end_position,strand,ensembl_transcript_id,transcript_start,transcript_end,ensembl_exon_id,exon_chrom_start,exon_chrom_end which does include attributes from multiple pages. If the I remove the attributes from the structure page, I don't get an error. I did see the post (http://www.mail-archive.com/[email protected]/msg02381.html) saying this feature (supporting exportable with attributes from multiple pages) is not supported in BioMart 0.7. How did Ensembl get around this? See : http://www.biomart.org/biomart/das/default__hsapiens_gene_ensembl__ensembl_das_chr/features?segment=13:31787617,31871805 Thanks, -Kiran
