Normalize for changes in one direction
... Hi, I'm trying to measure RNA stability changes after knocking out a repressor RNA binding protein. I'm using 4sU to label nascent RNA and also collecting total RNA as per this paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3114636/. I can then calculate RNA stability by the ratio of nascent RN ...

Comment: C: Non-used samples changing number of significant genes in limma
... I tried it with both voomWithQualityWeights and voomWithQualityWeights(var.design = design). This is what the plot looks like for the second one: https://imgur.com/HDhOUhQ. The order is: ko 1 high ko 1 low ko 1 mono ko 2 high ko 2 low ko 2 mono wt 1 high wt 1 low wt 1 mono wt 2 high wt ...

Non-used samples changing number of significant genes in limma
... Hi, I performed polysome profiling to measure translation rate in wildtype and knockout cells. For the polysome samples I collected a monosome fraction, a low polysome fraction, and a high polysome fraction. I also collected mRNA for both wildtype and knockout. I'm interested in comparing translati ...

pintersect and psetdiff changed behavior
... Hi, I had code to extract exons, introns and exon-intron boundaries from about a year ago. However, when I went to re-run it I now get the following two errors. Did the behavior of these functions change? I'd like to take the range of exons in a gene (union of all isoforms) and define everything in ...

RNA-Seq metagene coverage
... Hi, I'd like to calculate RNA-Seq meta read coverage over different subsets of genes similar to the genebody coverage function in RSeQC (http://rseqc.sourceforge.net/#genebody-coverage-py). I saw a number of packages that will do this for genomic coordinates, but I'm looking for something that will ...

RSEM expected counts to limma-voom
... I'm interested in analyze some RNA-Seq data from Encode. They have posted a gene quantification file for each sample from RSEM. My understanding is that I can pass the expected counts to voom and then limma even though raw counts is more ideal. I just wanted to check that this is correct? Thanks ...

Answer: A: matchPWM on DNAStringSet rather than just one sequence?
... That works, but is incredibly slow once I start looping through all of my UTRs and even a few RNA binding proteins. Is there another bioconductor package or program outside that would be significantly faster? ...

matchPWM on DNAStringSet rather than just one sequence?
... I have a couple PWMs for RNA binding proteins and I also have the sequences of candidate UTRs in different groups as a DNAStringSet. I'd like to see how many of the UTRs (and which ones) in each group match a given PWM. However, it looks like the matchPWM function in Biostrings only supports a singl ...

Reorder exons on negative strand in GRanges list
... I am trying to make a fasta file of reduced exon sequences (collapse all isoforms of a gene into one transcript). I'm running into a problem where exons on the negative strand are listed in ascending order based on chromosome coordinates, but this results in the exon sequences being written in the w ...
