Hello FSL Experts,
I have an FA data set in which I found a significant region of interest when overlaying one of my corrected tstat files (tbss_tfce_corrp_tstat2). However, when I load the uncorrected file (tbss_vox_p_tstat2) I find no significant regions when setting a threshold at p < 0.001 (I do see more regions at 0.003). That said, I am a little confused as to how I can have a significant region using the corrected tstat (~0.046) but no significant regions at 0.001 for the uncorrected tstat. Does cluster size impact the uncorrected output?
Cheers
