Hello Gang et al.,
I have a 3dLMEr modeling question I am hoping you may be able to help with.
Is it possible to specify multiple contrasts in one model? Essentially, we have a Negative, Neutral, and No Distracter (none) condition. We want to first contrast both distracter conditions with the no distracter conditions, and then contrast the results with each other: (Negative > None) > (Neutral > None). Could we use something like this in the 3dLMEr model specification: -gltCode neg-neu ‘emotion : (1neg -1none) - (1neut -1none)’
Thank you in advance!
