After nearly 6 months of review and revision, iMap4 is finally accepted in Behavioral Research Methods!
Lao, J., Miellet, S., Pernet, C., Sokhn, N., & Caldara, R. (2016). iMap4: An Open Source Toolbox for the Statistical Fixation Mapping of Eye Movement data with Linear Mixed Modeling. Behavior Research Methods. doi: 10.3758/s13428-016-0737-x
We got some very good (and some of them quite difficult) comments from an anonymous reviewer and Simon Barthelmé (he signed his own review, much respect!)
We might add a few more features for importing data and data visualization in the future, but the modeling procedure would likely remain. I am actively pursuing the Bayesian approach and generative model now for eye movement analysis, I think opening a new project would be more appropriate.
Until then, please try iMap4 and let me know what you think!
