Dear SPM list,
I am interested in the relation between BOLD response and drug dose. When I do a covariate analysis on my group of 18 participants in SPM5 (one-sample t-test with drug as covariate), I find significant voxels indicating a significant correlation. I would like to produce a scatterplot between the parameter estimates (betas) and drug dose at a significant voxel. Is it possible to obtain the betas of each participant at the voxel I'm interested in and which SPM uses to determine significant correlations? I'm guessing there is a variable somewhere which contains this data since I can find the variable which contains my drug dose data (SPM.xC.rc)
Ta,
Rich.
