Hi,all: I was using mri_glmfit-sim for multiple correction,but I'm wondering if --3paces could influence the correction result. From the website I saw the explanation below: mri_glmfit-sim --glmdir my-glm.wls --cache 3 pos --cwpvalthresh .0166 Using a cluster-wise p-value threshold of p < .0166 corrects across all three spaces for p<.05 (ie, .0166 = .05/3). This corrections for a whole brain (ie, lh, rh, and subcortical) analysis. Also,from the help document I saw: --3spaces : additional Bonferroni correction across 3 spaces (eg, lh, rh, mni305) So, I'm wondering if the command: ' mri_glmfit-sim --glmdir my-glm.wls --cache 3 pos --cwpvalthresh .0166 ' same with the command: ' mri_glmfit-sim --glmdir my-glm.wls --cache 3 pos --cwpvalthresh .0166 --3spaces ' or same with the command: ' mri_glmfit-sim --glmdir my-glm.wls --cache 3 pos --cwpvalthresh .05 --3spaces '.
If there is anyone know this question clearly, please reply me. Many thanks. Best regards. Han
