48 Replicate RNA-seq experiment

48 Replicate RNA-seq experiment

I and other members of the team have talked about this work at meetings over the last 18 months, but today the first of three (hopefully four) papers about a 48 biological-replicate RNA-seq experiment from my group (www.compbio.dundee.ac.uk),  the Data Analysis Group (www.compbio.dundee.ac.uk/dag.html), and collaborators Tom Owen-Hughes, Gordon Simpson (http://bit.ly/1JobrGZ)  and Mark Blaxter (http://bit.ly/1GXtC8M) was submitted to a journal and posted on arXiv (http://arxiv.org/abs/1505.00588). The data generated for this experiment has also been submitted to ENA and should be released in the next few hours.

Clearly, referees will have things to say about our manuscript, but I thought it was worth writing a brief summary here of the justification for doing this work and to provide somewhere for open discussion.

Briefly:

Paper I: The paper submitted today, deals with the statistical models used in Differential Gene Expression (DGE) software such as edgeR and DESeq as well as the effect of “bad” replicates on these models.

Paper II: Will be on arXiv in the next day or so, and benchmarks the most popular DGE methods with respect to replicate number. This paper leads to a set of recommendations for experimental design.

Paper III: Is in preparation, but examines the benefits of ERCC RNA spike-ins to determine concerted shifts in expression in RNA-seq experiments as well as estimating the precision of RNA-seq experiments. There will be an R-package accompanying this paper.

The main questions we were aiming to answer in this work when we started it 2 years ago were:

  1. How many replicates should we do?
  2. Which of the growing number of statistical analysis methods should we use?
  3. Are the assumptions made by any of the methods in (2) correct?
  4. How useful are spike-ins to normalise for concerted shifts in expression?

The aim with the experimental design was to control for as many variables as possible (batch and lane effects and so on) to ensure that we were really looking at differences between DGE methods and not being confused by variation introduced elsewhere in the experiment. This careful design was the result of close collaboration between us, (a dry-lab computational biology group), Tom Owen-Hughes’ yeast lab at Dundee, and Mark Blaxter’s sequencing centre at Edinburgh.

This experiment is probably the highest replicate RNA-seq experiment to date and one of the deepest. I hope that the careful design means that in addition to our own analysis, the data will be useful to others who are interested in RNA-seq DGE methods development as well as the wider yeast community.

    Extremely useful. Thanks Geoff.

    Thanks Nicolas! Hopefully you will enjoy Paper II as well – coming soon!

    Hi Geoff,

    The paper indicates that there is a total of 96 samples (48 of each type), but the ENA and SRA records have 672 total samples (or 336 of each type). Was a subset of samples used for these studies? If so, should those samples be noted in the publication or as supporting materials?

      Hi Robert,
      As I replied on twitter, the difference in numbers is because we split each replicate across 7 lanes in the HiSeq. This gave us technical replicates and allowed us to check for batch effects and so on. The full experimental design is explained in the Methods section of the Differential Expression Tool evaluation paper we posted on arXiv (See blog on Paper II). We are working with ENA to try to improve the metadata that explains our datasets in the archive. We will also deposit the processed data that our analysis is based on in an appropriate repository in due course as well as the code that did it.

      I hope this helps, but if you have other questions, don’t hesitate to ask!

      All the best,

      Geoff.

        That helps. I noticed that the XML for the data on ENA has the submission file name, which does look like it indicates the sample and the technical replicate, so I may end up parsing that.

        Of course, while working with ENA to get more meta-data up, you could put a file on figshare or github that gives the ENA accession to sample-lane replicate information ….

    Appreciate the example of using correlation heat maps to determine problems, as well as the other metrics that indicate possible problems, I know I will try them on my own -omics data (transcriptomics and others).

    I am curious why you wouldn’t use a grayscale map instead of heat??

    Why didn’t you calculate correlations between the individual lanes, as well as put ALL of the samples (biological and technical reps) in a single heatmap? This would show if there were lane problems, sample label mixups, etc, and give a high level overview of the data, as well as show if the within condition correlation is in general better than the between condition correlation. It would be large, but I think as a first pass overview it is useful, and then can be drilled down into within conditions for detail.

      And as I read it over again, I see why. All 96 samples were run on all 7 lanes, and then demultiplexed at the far end to generate the ~600 fastq files. Hmmm, curious if there is any use in calculating correlations using lanes in this situation. Will have to think about this some more.

      Hi Robert,

      We actually did thes very early on in the data analysis. It was somewhat informative but we found it because pretty tricky to compare sample correlations with so much spacing between them – it really is quite large and getting the overarching comparisons was a bit tricky. Once we could demonstrate that the variation between lanes was purely Poisson fluctuations, we really didn’t think there was much point in plotting it this way any more.

    The ENA metadata is going to take a while to sort out, but for now here is the mapping between accession number, lane, sample and biological replicate.

    I hope that clarifies things, but if not please get in touch.

    All the best,

    Geoff.

    thanks a lot for the very interesting paper both on the statistical models as well as the one about how many biological replicates are needed. I have found both of them very worth reading. I would really like to know, how you did the statistical calculations in the paper about the statistical models. Is there also an R package (or a script for that matter), which I might be allow to adapt to my data set.

      I’m glad you found the papers helpful. We put the code up on github under https://github.com/bartongroup/profDGE48 so you should be able to find what you need there. If you have further questions, then please email the first authors on each of the papers and cc me.
