Comment: C: Error while using champ.svd() function in subset of data
... Hi, The general idea is that any column in your phenotype matrix that might be mistakenly considered a numeric, but is actually a factor, like Slide, should be coerced as a factor in the matrix at some point before starting the analysis. This happens for Slide because it just looks like a big inte ...

Answer: A: annotatr: CpG Island/Shore/Shelf IDs
... Hi Stephany, Thanks for this suggestion. I think this is a good idea, but I'll need to spend some time thinking about how to do this because there are cases (I'm fairly sure) where islands may be close to each other and so they could potentially share a shore or shelf. Nevertheless, I'll put this ...

Comment: C: CpG site not annotated with annotatr
... Hi Sol, Since it is upstream, my guess would be that it would show up in the 1to5kb annotation. The promoter annotation only extends 1kb upstream from the TSS. I verified in the UCSC Genome Browser for hg19. As for the list of other CpGs, I looked at a handful at random and they seem to primarily ...

Answer: A: CpG site not annotated with annotatr
... Hi, Thanks for using annotatr. If it were 4kb upstream of a gene, I would answer that it falls in the 1to5kb regions, which is distinct from the promoters. However, you said 4kb downstream which suggests that it should probably be intergenic. To help me figure this out, could you give me the locati ...

Request to remove requirement for gr to have widths 1 in BSseq constructor
... Hi, I'm a big fan of bsseq because it is exactly the data structure I need for a package I maintain (methylSig) that tests for differential methylation (at CpGs and over regions). As of the Bioc 3.7 release it appears that a check in the BSseq constructor was added (I don't see a reference to it in ...

Strange error in bsseq when trying to assign seqinfo
...   Hello, I'm having a strange issue in R 3.5.0 / Bioc 3.7 when trying to assign seqinfo to a bsseq object that I don't have in R 3.4.3 / Bioc 3.6. The particular error I get can be reproduced with the following code: # Do not load any libraries seqinfo_hg19 = GenomeInfoDb::Seqinfo(genome = 'hg19 ...

Answer: A: ENSEMBL database for annotatr
... Hello, Correct, annotatr uses the UCSC knownGenes database. If there was a TxDb package for hg19 that used ENSEMBL as its basis, it would be fairly easy to create the annotations, but I am not aware of such a TxDb package. As to your question about read_regions(), my understanding is that 1 is add ...

Answer: A: Unexpected results from annotatr
... Hello, The annotations in annotatr include all the transcripts for a particular gene. In this case Got1 has an annotation for knownGene transcript uc008hoj.1 as 1to5kb upstream of a TSS, and it overlaps an intron that transcript uc012bmb.1 has. And in this case, your input region intersects both of ...

Answer: A: 'fill_order' in annotatr
... Hello, "fill_order" to the ordering of the bars in the bar chart, and also the legend. annotatr doesn't do a prioritization, really. It reports all the intersections of a region with annotations. So if a region is in both a UTR and CDS, it will count towards each of those categories in the bar char ...
