If you want to apply etiv correction when extracting the cortical volume with mris_preproc, just add --etiv to the command On 12/14/2020 9:59 AM, Sara Lyn wrote: External Email - Use Caution Hi Thank you for your response. How do I correct this extracted volume for intracranial volume

When you run the thickness analysis with multiple comparisons correction (mri_glmfit-sim), it will create "ocn" files. These will be clusters of the significant areas. You can use this to extract other information. If you want volume, then run mris_preproc using the --meas volume flag, the apply
