Additional information on WhatsApp and Facebook variables (median and interquartile range) (Christian Montag, 04 September 2015)

As the distributions of WhatsApp and Facebook variables are highly skewed, we also would like to provide the readers with the median and IQR of these variables to complete the picture on the dataset: WhatsApp/daily use in minutes: 21.23 (IQR: 36.15) Facebook/daily use in minutes: 9.25 (IQR: 22.93) read full comment

New repository for source code (Stinus Lindgreen, 17 March 2015)

I am the author of the paper "AdapterRemoval: easy cleaning of next-generation sequencing reads". When the paper was published, I made the source code available using Google Code. However, Google is shutting down this service in August 2015, so I have migrated the code to GitHub instead:

Corrections to equations 16 and 17. (Hui Kian Ho, 07 January 2015)

It was brought to our attention that equations 16 and 17 (the equations for recall and precision) contain typographic errors and should be amended as follows: Equation 16: recall = TP / (TP + FN) Equation 17: precision = TP / (TP + FP) These amendments do not change the results or conclusions of this article. read full comment

Mistake in table 1 (Frank Döring, 17 September 2014)

The description of the lines “ubiquinol” and “ubiquinone” are interchanged which means that the data/level of ubiquinol have to be allocated to ubiquinone and vice versa.

The limma model is not correct; see the updated paper at Colin's site for a correction. (David Airey, 05 September 2014)

The design in the original paper repeatedly samples 6 flasks over 5 time points, rather than 30 flasks grown to different time points where each flask is sampled once. The latter design might be appropriately analyzed by the limma code presented in the paper, whereas a better comparison for the actual design with the "timecourse" package would be to consider hierarchical designs in limma. The design of the actual experiment is a simple split plot, with the one between subject (flask) factor being strain and the one within subject (flask) factor being time. The fix here is to note the correspondence between the example in section 9.7 of the limma manual. Substitute time for tissue, and flask for subject, and strain for condition and proceed as shown. read full comment

Minor correction to sequence data (Cameron Neylon, 25 March 2014)

In table 1 the generation of two variant β-glucuronidases with increased β-galactosidase activity (labelled as C4.1 and C4.2) is described. Further analysis of the sequencing of these mutants has revealed a minor error in the listed mutation sites. Mutant C4.1 also contains a silent mutation. Mutant C4.2 is missing mutation sites N166T and N412D and the listing of a silent mutation. These make the mutants: C4.1: G245A/K370R/W529L C4.2: V67D/N166T/K370R/N412D/W529L These changes do not affect the overall results and conclusions of our report.

Positive Proof of Etiological Agent is Absent (Chester Cooper, 25 March 2014)

To be blunt, the central premise of this report is seriously flawed.  The authors claim to have isolated P. marneffei from an AIDS patient in Togo who had never visited the established and delimited endemic region.  If true, this would suggest that the fungus resides elsewhere in the world – a fact that has not been established in the nearly 55 years since this organism was discovered.  Unfortunately, the authors do not unequivocally prove they have isolated P. marneffei from this patient.  While I realize that resources might have been limited to these investigators, the conclusions they state rely on very dubious observations.  They point to the isolation of a fungus that does have... read full comment

typo (Jeruza Neyeloff, 10 April 2013)

Dear Vishnu,

You are correct. If you use the formulas from the additional file everything should work fine.

I am glad the paper was helpful and that you've learned from it.

Response to GAPP Comment (Jeffrey Lacasse, 14 December 2012)

We appreciate the response [1] from members of the Global Alliance of Publication Professionals (GAPP) regarding our recent article on ghostwriting [2]. The GAPP website notes that GAPP's aim is to "Provide a timely and credible response to influential stories about medical publication professionals" [3]. The GAPP website is funded by the International Society for Medical Publication Professionals [4], which is in turn funded by pharmaceutical companies [5]. In other words, GAPP's mission is to lobby on behalf of medical writers and publication planners subcontracted by the pharmaceutical industry [6-9]. We appreciate that this is transparent on the GAPP website.... read full comment

Interesting Case Report but 3 worrying things: (Christopher Weatherburn, 22 August 2012)

1. The case did the rapid testing after unprotected anal sex with the trial subject.
2. Misuse of methamphetamine prior to testing.
3. Divergence of kit used for trial.

I suspect the individual's character is likely to be the main factor that will relate to relatively responsible self-reported post result behaviour.

I have never seen the particular kits but would recommend they include clearer instructions regarding what to do after the result (particularly positive result with contact details for ongoing care). I suspect that for the purposes of your trial these may have been altered. Is this true?

I also suspect an increase use of HIV home test kits could help to destigmatise HIV in future. read full comment

Not a bug (Adam Szalkowski, 24 May 2012)

Dear Erik,

thank you for your comment but I still do not consider your use case being a bug as you probably swapped the gap opening and gap extension penalties in your command line. The gap opening penalty (-i) is the penalty that is subtracted from the score when a gap is opened and should be at least as large as the extension penalty (-e).

Depending of you definition of opening/extension penalty you probably should have said:
/tmp/swps3 /tmp/matrices/blosum50.mat /tmp/test/query0100.fa /tmp/test/udb1000.fa -j 1 -i -10 -e -3
/tmp/swps3 /tmp/matrices/blosum50.mat /tmp/test/query0100.fa /tmp/test/udb1000.fa -j 1 -i -13 -e -3

SWPS3 algorithm is buggy (Erik Sjölund, 08 May 2012)

A drawback of SWPS3 is that its algorithm is buggy. It sometimes gives the wrong result. For details see

The bug was reported In 2009 to Adam Szalkowski who acknowledged that the bug was reproducible.
As of March 2012 the SWPS3 software still contains the same bug. read full comment
