MAGIA pipeline for PET neuroinformatics

The MAGIA toolbox is designed for swift automated preprocessing of PET data with multiple ligands and models. he MAGIA implements automatic image retrieval from PACS combined with functions from FreeSurfer and SPM image preprocessing pipelines coupled with in-house PET modelling and metadata annotation code. Quality control is performed with in-house code and MRIQC toolbox. The compilation of MAGIA code is site-independent and can be installed anywhere.

emBODY

Emotions and other sensations are often experienced in the body. The emBODY tool can be used for mapping emotion-dependent sensations (or any other feature such as pain!) in distinct bodily regions. This online data acquisition and analysis package was originally used in Nummenmaa, L., Glerean, E., Hari, R., & Hietanen, J.K. (2014). Bodily maps of emotionsProceedings of the National Academy of Sciences of the United States of America, 111, 646-651.

Sorting tool for fast similarity ratings

Many psychophysical, neuroimaging, and analytic (e.g. RSA) techniques necessitate obtaining the similarity structure of the stimuli, traits or phenomena under scrutiny. Direct pairwise ratings are the usual gold standard, but this becomes prohibitive as the number of tokens increases even slightly over 10. This can be circumvented using Q-sort like arrangement task, where the tokens are spatially arranged in a grid based on their similarity. This is an online implementation of the arrangement task as originally used in Nummenmaa, L., Hari, R., Hietanen, J.K., & Glerean, E. (in press). Maps of subjective feelings. Proceedings of the National Academy of Sciences of the United States of America.

Dynamic annotation web-tool

When working with high-dimensional stimuli such as movies or speech, the stimulus model has to account for intensity and temporal fluctuations. This is a web implementation of dynamic stimulus annotation toolbox originally used in Nummenmaa, L., Glerean, E., Viinikainen, M., Jääskeläinen, I.P., Hari, R., & Sams, M. (2012) Emotions promote social interaction by synchronizing brain activity across individuals. Proceedings of the National Academy of Sciences of the United States of America, 109, 9599–9604.
