Reconstructing phylogenies is an interesting task, sadly one that often requires to navigate between a multitude of software. To add an unnecessary layer of complexity to the whole thing, most of these softwares speaks different languages, and requires the user to do endless conversions from fasta to phylip to nexus to whatever new format they

Changing phylogeny tip labels in R

During the process of molecular systematic research, specimens are given code names and numbers to keep track of data through the pipeline. These can contain a lot of information of relevance to the researcher, but unfortunately are meaningless to others who aren't as involved with the data. On publication, it is necessary to change the names from the code...

Adap’skiii [day 2]

Another exciting day at Adap’skiii!!! Yves Atchadé presented a very recent work on the fundamental issue of estimating the asymptotic variance estimation for adaptive MCMC algorithms, with an intriguing experimental observation that a non-converging bandwidth with rate 1/n was providing better coverage than the converging rate. (I always found the issue of estimating the asymptotic

Overall, the blog has doubled the average number of daily visitors and pageviews compared to 2009. The number of pageviews varies quite a lot, as you can...
