Hello,
I would like to inquire about using DESeq2 package in order to compare different types of read data:
1. Would it be OK to use DESeq2 to compare read data between homologous genes in different strains of the same bacterial species?
2. In case I would like to analyze only a subset of the genes, classified by a certain independent feature - Would applying DESeq2 to only a subset of the genes be OK or would it affect the normalization?
3. We have recently developed in our lab an experimental methodology termed RIL-seq (Melamed et al., Mol. Cell, 2016) to find small RNA-target interactions. By this methodology we ligate RNA fragments and sequence them by paired end sequencing. In the mapping procedure we identify chimeric fragments, in which one read belongs to one RNA molecule, and the second read to another RNA molecule. My question is if it would be OK to compare the numbers of chimeric fragments of corresponding pairs between different growth conditions using DESeq2 (we have several samples for each condition).
Many thanks in advance,
