Occasionally, the MRI Core identifies preprocessed data through the Quality Control Process that is incorrect. In such cases, the MRI Core, through LONI, will make an attempt to contact institutions that have downloaded data identified as incorrect. All investigators should regularly check this site for recall notices and remove data previously downloaded for analysis until corrected data has been posted.
