Hi Hernan - I should have been a bit more specific that its your work Iâve been looking at (I set my task to get a graph for a specific country - and was able to figure out how to do that reasonably easily but hard coded for my experiment so far). I now see that Alex has added some thoughts on Roassal which Iâm keen to look at next. Anyway, thanks for doing this and sharing it.

Re: [Pharo-users] Corona virus

by HernÃ¡n Morales Durand

Hi Tim, and others Some weeks ago I started a GitHub repo for COVID-19 analysis with Pharo : https://github.com/hernanmd/COVID-2019 A good mindset before digging into the massive amount of info is to define what you can/want to do: 1 - In detection & diagnosis (if you understand CRISPR, Nanobiosensors, Direct Fluorescent Antibodies, RNA Aptamers, you can help now) 2 - In prevention (doing flyers, visualizations, cards from official sites: see below) 3 - In treatment & therapeutics: The calendar for clinical trials is set and laboratories are working in Drug testing now. If you can discover novel information (through Deep/Machine-Learning of drugs like Remdesivir, Tocilizumab, other monoclonal antibodies or anti-virals, immunoglobulins) it would be an advance. Right now I have some text-mining analysis but I did it in Python as they have more NLP libraries, but working with lab notebooks is crashing all the time because of memory issues). Feel free to add issues, requests or code. Examples: - Some state of the art analysis seem to involve manual processing: https://github.com/galaxyproject/SARS-CoV-2/tree/master/1-PreProcessing#the… (this changes because DNA sequences are added as sequencing centers uploads more) - From here : https://www.ncbi.nlm.nih.gov/genbank/sars-cov-2-seqs/ you can see a list of "SRA sequences".

[Roassal3 Script of the day] Visualizing Coronavirus official public data

by Alexandre Bergel

Hola, Here is a script, for which I hope some of you will find useful. The script of today visualize the number of infected and allows for an easily (and very basic) comparison. First, you need Roassal3 and DataFrame. Here is the code: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Metacello new baseline: 'Roassal3'; repository: 'github://ObjectProfile/Roassal3'; load. Metacello new baseline: 'DataFrame'; repository: 'github://PolyMathOrg/DataFrame:v2.0/src'; load. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Then, evaluate the Pharo code available on: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= https://gist.github.com/bergel/6ebcde9696ef922f2b519c56a4520bac -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= You should then see the following: Change the names of the countries to see what you are interested in.
