Hello Freesurfers, I am currently using func2roi to analyze the hemodynamic response to a cognitive task within the dACC in a group of subjects. I have been constraining my analyses to 6 seconds post stimulus onset, a specific contrast (error_vs_correct), and with a very low threshold so

Hello Freesurfers, I am currently running ROI analyses (dACC) and want to plot the timecourse of hemodynamic responses to a cognitive task (2 conditions) in a group of subjects. I have been using func2roi commands such as func2roi-sess -roidef lh_dACC -analysis RM_correct_error -anatlabel
