I don't mean to pick on CDC. County Health Rankings is an awesome website that aggregates and releases for download public health data from a variety of sources. I'm grateful for that, but the Excel files they release each have multiple sheets, nested headers, merged cells, and extra columns with confidence intervals. It's pretty much impossible to analyze that data in a program other than Excel. To do so, I first have to manually select and reformat the data I want, rename the variables, and then copy/paste it into a new file - which rather defeats the purpose.

Simple Statistics with PHP By bastian, on June 9th, 2011 I work as researcher and one of my day to day duties is processing measurement results and producing some nice graphs to make the results visible and understandable. Although most of the processing is very specific to particular experiment, general statistics functions are needed ever so often. Out of habit, I usually use PHP to process my log file. Although PHP was certainly not intended for such purpose, I tend to use it very often for small command line scripts that just would take too long to write and debug in bash. I know, that probably python is the scripting language of choice for these applications, but I did not find the time to dig into python far enough to quickly hack together the necessary scripts. Anyway, to make life of others easier in the future, you can find the functions that I use to calculate the median, the average, the standard deviation as well as the different quartiles below. These functions exp...

SIFT predicts whether an amino acid substitution affects protein function. SIFT prediction is based on the degree of conservation of amino acid residues in sequence alignments derived from closely related sequences, collected through PSI-BLAST. SIFT can be applied to naturally occurring nonsynonymous polymorphisms or laboratory-induced missense mutations.
