Herve, Thanks so much for digging into this. Rhonda, I had submitted a ticket as suggested to Ensembl helpdesk, and have included them as recipients to this message (after changing the subject to include the issue tracker number). Ensembl helpdesk, I expect that Herve's detailed report, below, provides an example of the reported data anomaly that will help resolve the underlying issue.

Hi Malcolm and Hervé This appears to be a data issue with the Drosophila core database which was then propagated into BioMart. I have forwarded the issue to the Ensembl Genomes project as they maintain this database and they will respond as soon as possible.

Dear helpdesk at ensemblgenomes.org, I am following up on this issue which I understand Rhoda Kinsella at EBI to have forwarded to you. I originally identified and reported the issue, first to the bioconductor email list where Rhoda picked up on it and replied as below. I am trying to ensure that there is a tracked issue with ensemblgenomes.org with my name on it ? not that it has to be resolved with a fix, just I'd like to be assured I know as you resolve it. If there is anything further I can provide pertaining to describing or resolving the issue, please advise. Of course the issue may be in fact even further upstream ? in flybase. I've not tried to find the root cause myself.

This appears to be a data issue with the Drosophila core database which was then propagated into BioMart. I have forwarded the issue to the Ensembl Genomes project as they maintain this database and they will respond as soon as possible.

Rhonda, I had submitted a ticket as suggested to Ensembl helpdesk, and have included them as recipients to this message (after changing the subject to include the issue tracker number). Ensembl helpdesk, I expect that Herve's detailed report, below, provides an example of the reported data anomaly that will help resolve the underlying issue.

Take for example the FBtr0079414 transcript (minus strand): library(biomaRt) mart1 <- useMart(biomart="ensembl", dataset="dmelanogaster_gene_ensembl") attributes <- c("ensembl_transcript_id", "strand", + "rank", "exon_chrom_start", "exon_chrom_end", + "5_utr_start", "5_utr_end", "3_utr_start", "3_utr_end", + "cds_length") filters <- "ensembl_transcript_id" values <- "FBtr0079414" getBM(attributes=attributes, filters=filters, values=values, mart=mart1) ensembl_transcript_id strand rank exon_chrom_start exon_chrom_end 5_utr_start 1 FBtr0079414 -1 1 7218909 7220029 7219112 2 FBtr0079414 -1 2 7218643 7218853 NA 5_utr_end 3_utr_start 3_utr_end cds_length 1 7220029 NA NA 204 2 NA 7218643 7218853 204 2 exons: The 3' UTR (located on exon 2) spans the entire exon so no CDS on this exon. The start of the 5' UTR (located on exon 1) is 203 bases upstream of the exon start. But the reported cds_length is 204. Something looks wrong. For other transcripts, e.g. FBtr0300689 (plus strand), things look OK: getBM(attributes=attributes, filters=filters, values=values, mart=mart1) ensembl_transcript_id strand rank exon_chrom_start exon_chrom_end 5_utr_start 1 FBtr0300689 1 1 7529 8116 7529 2 FBtr0300689 1 2 8193 9484 NA 5_utr_end 3_utr_start 3_utr_end cds_length 1 7679 NA NA 855 2 NA 8611 9484 855 2 exons: The end of the 5' UTR (located on exon 1) is 437 bases upstream of the exon end. The start of the 3' UTR (located on exon 2) is 418 bases downstream of the exon start. So the CDS total length is 437 + 418 = 855, as reported. @Malcolm and other makeTranscriptDbFromBiomart() users: I'm about to commit a patch to this function so that this anomaly in the Ensembl data causes a warning instead of an error. Also the warning will display the first 6 affected transcripts. The patch will make it into GenomicFeatures 1.6.8 (release) and 1.7.14 (devel), which will become available via biocLite() in the next 24-36 hours. Cheers, H.

I'm planning to patch the code in charge of this sanity check so it issues a warning instead of an error and it displays something more useful than just "for some transcripts etc...". Would be nice to know at least for which transcript. I'll keep you informed, thanks! H.

Error in .extractCdsRangesFromBiomartTable(bm_table) : BioMart data anomaly: for some transcripts, the cds cumulative length inferred from the exon and UTR info doesn't match the "cds_length" attribute from BioMart Marc, you already observed that: the data for cds ranges and total cds length (both from biomaRt) no longer agree with each other. In other words, the data from the current drosophila ranges in biomaRt seems to disagree with itself, and so the code is refusing to make a package out of this data as a result. To get the 2nd issue fixed probably involves talking to ensembl about their CDS data for fly to see if we can resolve the discrepancy. I would be happy to take this to them. I still wonder: Can you recommend a best way to get a more diagnostic trace from the attempt at txdb creation so we can correctly report to ensembl team the errant transcript(s) ? I would be happy to take this up with Ensembl team, but, need details which I don't know how to produce. Finally, one the side, here is a tiny suggestion: * change the default for circ_seqs in makeTranscriptDbFromBiomart to be NULL, instead of any organism (human) specific.
