Bowtie2: trying to implement position specific scoring options?
... Hello all, Question: Is there a way to have bowtie2 give an alignment a score boost if specific regions of the read mapped perfectly? For example, say I have a 24nt read and I am using bowtie2 in –very-sensitive-local mode, if there is a match from positions 2-8 (from the 5' end of my read) I want ...

GOstats Clarification: ontology information source
... Hey everybody, I am wondering what ontology file (.obo file) GOstats uses and where I could view it. Does GOstats pull its ontologies from geneontology.org (e.g. http://purl.obolibrary.org/obo/go.obo ) or is there some other source? I started looking at the source code but I haven't been able to pi ...

Comment: C: GO Analysis Clarification using GOstats using hyperGTest()
... Yes, there is no Tetrahymena specific file, but the file used to generate the universe for my analysis was downloaded from the [geneontology.org's annotation download page][1] with the filter "+ taxon_subset_closure_label: Tetrahymena thermophila SB210" to download all 34679 Tetrahymena annotations. ...

GO Analysis Clarification using GOstats using hyperGTest()
... Hey everybody, I have a question about how the hyperGTest() works with regard to the GO terms tested. From one of my results tables, some of the GO terms returned are not in my GO universe (the GO term is not in my organism's obo file). For example, this GO term was shown to be significantly enri ...

Decreased base quality at start of RNA seq reads
... Hey all, While running quality control steps for an RNA-Seq experiment I can see a decrease in the read quality score at the first few nucleotides (see below). ![enter image description here][1] I read the fastQC manual and it said on the Per [Base Sequence Quality][2] that poor quality at the sta ...

Clarification on how DSEeq2 Dispersion Curve is Generated
... Hi everyone, I have a clarification question on how the average expression versus dispersion curve is generated. From the paper, it says that Deseq2 uses 'all samples' in making the plot, but is that all samples for a given sample type (genotype) or is it all samples regardless of genotype? I am ...

RNAseq sva-seq drops number of DE genes?
... Hey everybody, I have a question about the Surrogate Variables Analysis(SVA) implementation. I have an RNA-seq dataset counts matrix that I am piping into DESeq2 to identify differentially expressed genes. When the RNA libraries were prepared the cells were grown in batches with one wild-type strai ...
