Dear Bioconductor List, I am new to RNASeq. I am running the script that comes with easyRNAseq a command at a time to learn the program. I got warning messages. I am wondering if they are indicative of something being wrong with my installation because I did not expect warnings in a tutorial script.

Dear Richard, The warnings are indeed there on purpose. In the first section of the easyRNASeq vignette, in the "usage" subsection, there's a paragraph entitled "Warnings" that explains their meaning. This paragraph is indeed missing from the RnaSeqTutorial vignette, I'll correct that, thanks for reporting it. In the example, 2 kinds of warnings are raised: 1) warning about overlaps in the annotation: Their goal is to make the user realize the danger of performing multiple counting if the annotation used are not adequate; i.e. assigning a sequence read to multiple features, e.g. to slightly different, yet overlapping exons. As this task can hardly be automated, it is left to the user to create an annotation set that would avoid such problems. I'm currently adding to the vignette a use case to do so. 2) warning about potential naming issue in the input file: It is (sadly) very frequent that the sequencing facilities use different naming conventions for the chromosomes they report in the alignment files. It is therefore very frequent that the annotation provided to easyRNASeq uses different chromosome names than the alignment file. These warnings are there to inform you about this issue. In version 1.2.3, these warnings were not very sophisticated, this has improved in the development version of easyRNASeq. I hope this clarifies your question. Thanks again for your feedback, I'll update the vignettes accordingly.
