Today was a very productive day. But something stood off, with a shiny feeling: a new tool for bioanthropologists is on the making.

That’s it folks. Osteomics is releasing a new app today, on one of the 4 basic pillars of Forensic Anthropology, one that we hadn’t explored yet: sex diagnosis. It is based on a famous article by Murail et al. (2005) that has probably the method with best balance between applicability and overall accuracy for sex estimation in osteology. Basically, we’ve implemented a new interface onto the same algorithm (that has been rewritten in R). Which is now, by the way, way faster than the original DSP Excell-based software.

It allows a case-by-case input, very useful if you are in the field, with your mobile phone or tablet, so you can access it and estimate sex right away. If you are doing more intensive laboratory work, it also has a population input mode through .csv tables upload, and it can calculate literally thousands of cases and generate an output of results in less than a second. Currently it is solely limited by internet access. This means, that contrary to DSP original version it is not Windows-exclusive, neither Excell-dependent!

Here is the link:

DSP: betteR, fasteR, strongeR!

Some print screens of DSP working in my iphone. The app allows you to do statistically significant sex estimations based on os coxae.

Since it is still on early stage (I will be adding a Manual with images tomorrow and other functionalities), I’d be very grateful if you guys tested it out, left any commentaries or try to crack it until you find some bugs for me to correct. After this starts to look as a final product, I will update it and add it to the Software section.

  • Manual with descriptions and pictures added;
  • Example dataset that works as a template for users to insert their data correctly, was also added;
  • Limited the number of minimum variables to 4 as in the original version of the software;
  • Corrected a lot of small bugs (calculations crashed under certains circunstances);
  • Added a lot of explanation texts here and there, and corrected some typos.

It is pretty much a final product by now. Any suggestions?

Today, I created a Zotero and Mendeley (.CSL 1.0.1) compatible reference style for the scientific magazines: Antropologia Portuguesa and Cadernos do GEEvH. My reason for doing this, is mainly because even though there was already an online version of this reference-style, it was only available for the paid-software EndNote. Since Zotero is free, it is definitely a more student-friendly option that I recommend to everyone. In the same spirit, I am sharing this for free to whoever might want or need it.

This .csl file uses the style described in Antropologia Portuguesa Guidelines. You can download it directly from here or by visiting the GitHub repo, an open collaborative coding platform where you can suggest modifications to the file.


  1. Install Zotero if you haven’t done so.
  2. Download the antropologia-portuguesa.csl from GitHub.
  3. Double click on the file.
  4. In Zotero’s settings, change your current style to “Antropologia Portuguesa”.
  5. You are ready to go!

Enjoy it.

My thesis, titled Unwarping Heated Bones: A Quantitative Analysis of Heat-Induced Skeletal Deformations Using 3D Geometric Morphometrics has spawn many fruits that are not a direct outcome of the quantitative analysis. In a open-science philosophy for further developing the global interest into the field of heat-altered osteology, during the next days I will be sharing with you most of what I have done during the last year. Ultimately, the full body of my thesis, as well as the data, will be available here on my personal page and in others, such as the HOT Project webpage which already counts with many interesting theses and articles by other colleagues.

Interactive 3D meshes of humeri

Below, you will find humeri in pairs of before and after experimental burning, respectively. You can click to interact with the 3D object and expand these to full screen. Currently you can zoom, rotate and move the mesh, as well as share this meshes on other media, such as Facebook.

Hello folks! I am back to the world of web development with this combination of a personal blog + portfolio-style page. The focus, as you can see is clearly on content. To help on that, the menu has been collapsed into a floating square at the upper-left corner. However in the menu is where you can find all the neat stuff. This will include my endeavors in anthropology, business, web design, and programming. Some stuff is already there, so check it if you feel like it. :)

The main reason for starting is that I have stuff scattered all over the web and old disks. Much has been lost over the years. So from now on, I will be moving all my works into this new home, as time allows me.

Another point I’d like to state is that having an opportunity to take some rust out of my HTML and CSS skills is something that I heavily took into consideration as well. Advancing my skills in javascript and Ruby, as a starter in both, is also a plus. Until now I’ve only played around with RGSS (a variation of Ruby), when I was really young and was trying to create some Role Playing Games. Moreover, the foundations of this site are product of Jekyll and everything is hosted in GitHub, so this is definitely the time and context for it.

Of course all that has been said are just motivational drivers. What I truly hope to accomplish here, is to recover a writing routine and become even more productive through peer pressure.

Yours truly,
