In HGT how have foreign sequences entered the human genome? (Kevin Smith, 23 March 2015)

I suggest that the most likely route by which exogenous sequences have entered the human genome is via sperm-mediated gene transfer. I hypothesised about this possibility previously, if interested please see Smith K. The Role of Sperm-Mediated Gene Transfer in Genome Mutation and Evolution. Medical Hypotheses, 2002; 59(4): 433-437.     read full comment

Correction: Segway no longer needs a computer cluster (Michael Hoffman, 16 March 2015)

Minor correction: since the release of Segway 1.2.0 on 29 August 2014, Segway will run on standalone computers not attached to a cluster.

Underlying mapping algorithm Batman still unpublished. (Alejandro Fernandez, 04 March 2015)

"After linker trimming, the tags are mapped to the corre-sponding reference genome using the Batman package (CTennakoon et al., manuscript submitted) with at most one mismatch."   I was unable to find references or any documentation regarding Batman, has this been documented? Does the tool work with BWA or Bowtie?    read full comment

Global levels of 5hmC vs. proliferation (Martin Bachman, 10 February 2015)

The relationship between 5hmC levels and proliferation has already been described and explained in detail here: 5hmC is restored on newly replicated DNA with a substantial time delay, and therefore in fast proliferating cells where a lot of new DNA is being synthesised, the global levels of 5hmC are diluted down.
Treatment with such high levels of Vitamin C (1 mM) will most certainly slow down proliferation and therefore partially restore levels of 5hmC. This also means that TET enzymes are still present and active in the cells, and their downregulation cannot be fully responsible for the observed "loss" of 5hmC upon placing primary cells in culture.

Important work in a very interesting paper. (Clement Kent, 02 February 2015)

Liu et al. use the power of whole genome sequencing of multiple haploid drones descending from the same queen to zoom in on where in the genome recombination events are happening. This paper is of special interest to social insect researchers because it suggests that the already high previous estimates of honeybee recombination rates may have been two-fold... read full comment

One billion views for WEHI YouTube? (Neil Saunders, 02 January 2015)

Because competence is a better qualification for leadership than loud shouting (Wolfgang Huber, 04 August 2014)

Thanks to Neil for raising two important issues, although as any decent philosopher, he only gives us the questions, not the answers:

  1. How do we best define a scientist's real value to the community?
  2. Why are there some people that have a much bigger followership than 1. justifies, and do we want that?
Unsurprisingly, the answer to 1. is  more subtle than just WoK citations. As for 2., there are many frustrating examples in the world of science that mirror the Kardashian-Syria example, and it'll be good for us to be mindful about them.   read full comment

The Kardashian index... why should we care? (Madhu Singh, 31 July 2014)

First, I should congratulate the author for getting attention of the editors of Genome Biology to even get this 'paper' published.  Next, I should congratulate the editors for thinking 'out of the box' to accept this manuscript.  It will surely increase the traffic, even if the journal doesn't need a boost in its impact... read full comment

Response to comment "comparison with the epigenetic clock by Horvath 2013" (Wolfgang Wagner, 27 February 2014)

Steve Horwarth has compared the method described in this article (Weidner et al., PMID: 24490752) with his recently published age-predictor (Horvath 2013, PMID: 24138928). This comparison is very interesting and helpful. We are grateful for this... read full comment

Comparison with the epigenetic clock by Horvath 2013 (Steve Horvath, 18 February 2014)

Weidener et al (2014) present an age predictor based on human blood methylation levels that only uses 3 CpGs. Last year, I published an age predictor (referred to as epigenetic clock) that works well in most human cells/tissues/organs (Horvath 2013, PMID: 24138928) but it makes use of 353 CpGs. Given that a sparse predictor has obvious practical advantages, readers may be interested in learning how the epigenetic clock compares to the predictor by Weidner et... read full comment

Please check the human cofilin-1 and cofilin-2 protein sequences in figure 2 of this paper (Yi-Jang Lee, 17 January 2014)

Dear Sir   I recently read this review paper for some reference purpose, and unexpectedly found that the sequence of H. sapiens cof-1 and cof-2 proteins in the figure 2 seemed to be listed oppositely.  I checked the PDB and genebank and confirmed this potent flaw. Please check it out. Thank you! read full comment

Table 2 erratum (Doron Betel, 04 November 2013)

There is a correction to table 2 that did not make it into the final version.
In the last row of table 2 called "Runtime for experiments with 3-5 replicates..." the values for edgeR and limmaVoom should be Seconds not Minutes.

For completeness, the following table is the runtime performance (in seconds) of six methods from DE analysis comparing the 5 replicates from groups A and B from the SEQC data.

DESeq | edgeR | PoissonSeq | limmaVoom | baySeq
user.self | 410.292 | 7.380 | 12.893 | 4.897 | 20.772

NIH support (Ariel Fernandez, 03 September 2013)

The research reported was incorrectly stated to have been supported by NIH grant R01 GM072614 "Protein packing defects as functional markers and drug targets" (NIGMS, PI: Ariel Fernandez). The work is thematically unrelated to the NIH grant and did not receive any NIH support. The author apologizes for the mistake.

Error rate is random (Mauricio Carneiro, 30 August 2013)

Hi Ravi,

The key concept you are missing here is that the error (despite high at 14%) is random, therefore proportional coverage helps makes the error rate irrelevant, no error correction method is needed other than a good variant caller with a bayesian model (hint: GATK). read full comment

multiplexed constructs (Jose L. Oliver, 22 July 2013)

Dear authors,

on page 10 of your paper you mention that you have `...identified 22 multiplexed constructs that drove GFP expression consistently at 24 hpf to at least one tissue (Figure 1d, Additional File 3). However, in Figure 1d you only labeled 6 of these constructs. Please, what are the labels of the remaining ones? Are they marked in some form on the excel file (additional file 3)?

Thanks in advance, sincerely,

Technical justification missing in the article (Ravi Shankar, 16 July 2013)

Well, the authors are correct that their is a huge apprehension in buying PacBio sequencers and they are surrounded by some negative publicity. However, this article appeared to be an academic attempt to bring PacBio sequencers in a good light. The entire article misses depth in dealing and really did not address a much technically to prove their points. If sequencing error is there with 14% or so, it is per base chance. Their error correction method is not convincing one, as they claim that they increase coverage to minimize the sequencing errors. This is not a right way and it can't remove innate errors per reads. It is like constituting jury of wrong people in majority, whose majority vote is counted to decide the point of agreement. So, these all jury members will finalize a sequence... read full comment
