How to upload your scientific software code to GitHub and get a DOI from Zenodo

This past weekend I had the pleasant experience of migrating my software KARDIA form its old home at the SourceForge repository to GitHub. Although the clearest benefit from this migration is the possibility to easier collaborate with other programers for the future development of the software, there are several other sweet candies that came along…

¿Qué es la Ciencia Abierta?

Muchos académicos todavía confunden Open Science con “Open Access” o, lo que es peor, creen que acceso abierto es sinónimo de publicar en revistas de acceso abierto. Este es el primero de una serie de posts en los que intentaré aclarar el significado y la relevancia del concepto de Open Science y explicar qué acciones sencillas podemos realizar los científicos para contribuir a generar una ciencia más abierta, transparente, eficiente y colaborativa. Empezaré ofreciendo mi visión personal sobre qué es la Ciencia, cuál debería ser su objetivo y cuál debería ser nuestra actitud para ayudar a que cumpla su función y contribuya a la sociedad de una forma más eficiente.

HEPLAB: Matlab scripts to facilitate heartbeat-evoked potential analysis

Last month my colleague Luis Ciria and I, gave a two-day workshop that focused on how to use the Matlab toolbox eeglab to create heartbeat-evoked events, extract epochs from the continuous EEG signal based on these events, and use Fieldtrip to perform a cluster-based permutation analysis to detect statistical differences between groups and conditions. The custom scripts we used at the workshop are freely available through the Zenodo repository.

Which side are you on boys?

As promised, I publish here a recent correspondence between Angel Correa, a colleague at the Brain, Mind & Behaviour Research Center of the University of Granada, and the editor of an Elsevier journal. I do not wish to express my opinion here —although the title and image of this post may be giving a hint— nor to reveal the identity of the editor. I prefer to listen to what my fellow colleagues think about which are the obligations and responsibilities of authors and journal editors in the emerging landscape of open scholarly communication.

How to detect the B point in impedance cardiography

Our new article, published in Psychophysiology and freely available from my Publications page, compares the accuracy of the three algorithms for B point detection included in Biopac’s popular software Acknowledge. We found unexpected and dramatic differences in the accuracy of these three algorithms, with the one based on the third derivative of the impedance cardiogram performing significantly better. In our article, we also provide a decision tree to help in the manual detection of the B point, especially by young and inexperienced researchers.
