Answer: A: DESeq2 Following RSEM
... The DESeq2 manuals says: "As input, the DESeq2 package expects count data as obtained", which means just handles whole numbers. I doubt that "round" is a good approach here, because you change the counts. Where does the e.g. 0.64 count from Sample1 A1BG come from? ...

Finding candidate binding sites for RNA binding proteins in R
...   Hi, I need to scan mRNAs for binding motifs of RBPs (RNA binding proteins) in human.  After some research I came across this tutorial on how to find candidate binding sites of known transcription factors. So far I did not saw an implemented tool to directly work with RNA or RBPs. I downloaded ...

Comparing two RNAseq experiments using summarizeOverlaps
... Hi,  I have two RNA-seq experiments. I first checked them to see whether they are single or pairedEnd using: bamtools view -c -F 1 myfile.bam, bamtools view -c -f 1 myfile2.bam There I saw that all reads are singleEnd. In the next step I uploaded my data in R, and counted the reads per feature by ...
