Hello,
I'm trying to load the results from a published paper that used CONN to look at how they ran their analysis (then hopefully follow their analysis steps with my own data). They have their raw fMRI and task onset data available open source and then all their resultsROI_Subject001_Condition001.mat files for their 2 conditions and 37 subjects. They don't have a conn_*.mat project file available I can load/look at. I wanted to know if there's a way I could load those 74 first level result resultsROI_Subject0**_Condition00*.mat files into CONN to view results in the GUI and their experimental set up without starting from the raw files and attempting to recreate the whole thing on my own. I also ran into a similar issue when my lab drive ran out of memory and my conn_*.mat project file got corrupted and I couldn't figure out how to load everything I had already run into a new project and ended up redoing it.
Relatedly - I'm doing all of this to try to figure out how to best handle my 3 conditions in my analysis - for each participant I have blocks of rest (just watching the task screen), control math task, and stressful math task and had been running analyses with the control, experimental, and rest conditions included in the first level gPPI conditions to be modeled and then did a [-1 1] "difference experimental > control" for the between-conditions contrast in the second level analysis. I'm not sure if I should instead be doing the [0 1 0] and "effect of experimental" for second levels. For my main analysis seed-based, the [-1 1] contrast seemed to produce logical results, but for the group ICA analysis using the [-1 1] contrast eliminated all results and I feel like that is incorrect theoretically for ICA.
Thank you,
-Rachel
