Hi Dr. Mumford- you have been a great resource for me this year- both your paper on LSS and your YouTube videos— thank you! On that note, I have been testing out CONN toolbox for use in gppi analysis and just found out it uses the fsl rather than spm method without deconvolution to create interaction terms. WHYYYYY. I have an event related design and was about to gear up to analyze all my subjects, after testing it out on one subject. Do you think this is a huge no no? Unfortunately time is a constraint, (I’m supposed to defend , like, tomorrow ) and don’t know if I have the bandwidth for figuring out spm and gppi toolbox. Up until now I’ve done all my standard univariate analysis in Afni, and it was already a huge jump for me to consider ‘starting over’ in CONN. Conn makes whole brain Roi to Roi analysis super easy- my plan was to run network analysis on the resulting ppi matrices. So I really really realllllly want to pretend I never learned about the whole ppi deconvolution debate. Any advise is appreciated...
