Set your RNA-Seq objective first, choose the proper library, and then decide how many reads you will need for it. So, before you start the RNA-Seq project, it is very important to define the objective of your project, whether to see the entire transcriptome of your samples including splic...
In addition, you need at least one aligner to align RNA-Seq reads for you. RSEM can call Bowtie, Bowtie 2 or STAR for you if you have them installed. Last but not least, you need to install the latest version of RSEM.In this tutorial, we align reads with Bowtie 2. We will ...
For many RNA-Seq-based projects, the budget for sequencing costs, and thus the total number of reads that can be obtained, is constrained. Thus, researchers designing RNA-Seq experiments must often determine the correct balance between sequencing depth (the number of reads per sample) and breadt...
b, MNase-seq analysis of stable nucleosomes in the GAL10 promoter region. The black arrow indicates a small shift of the +1 nucleosome into the NDR upon RSC depletion. MNase plots in a and b show one representative replicate out of two experiments. c, Schematic of PP7 RNA labeling to ...
Logic will help many details come back naturally. So when the context itself has mnemonic properties, don’t create an image for any word or phrase where context will make everything clear. But if you’re worried and do want mnemonics for each and every word, Robert Fludd suggests certain ...
Erythrocyte-derived microRNAs can account for up to 50% of all sequencing reads from blood, obscuring RNA transcripts of interest. When carrying out RNA-Seq, it can be desirable to remove these microRNAs as well as rRNA. Horos has been working with QIAGEN on a custom FastSelect reagent for ...
I have seen many posts regarding counts to RPKM and TPM. I haven't seen any post for counts to FPKM. I have RNA-Seq data which is paired-end reads. Extracted the counts using featureCounts for all the samples. There is a function to convert counts to RPKM: using the gene_length ...

For example, if one strand reads "GATC" in one direction, these DNA bases will pair up with "CTAG" on the opposite strand because G always pairs with C and A always pairs with T. When read backward, CTAG becomes the original sequence, GATC. These repeats are "regularly interspaced," me...
Another very well-known tool for RNA-sequencing analysis is DESeq2 [39], which performs count data normalization and differential analysis. Also in this case, normalization is done through data scaling for sample-specific size factors. To estimate these size factors, DESeq2 package implements the...
