Hi, freesurfer expert, I have three questions about the multiple correction. I performed the statistical analysis between two groups first in left hemisphere, and got some regions which showed different. 1) so if I then do multiple correction, i don't need to run the mri_glmfit-sim command, and

Hi Meng, if you are doing whole hemisphere correction, it will used already computed values which should only take a few seconds to run. doug On 07/05/2012 11:03 AM, Meng Li wrote: > > Hi, all, > > I have some questions about the multiple correction in qdec. > > I performed group analysis using q

Hi, all, I have some questions about the multiple correction in qdec. I performed group analysis using qdec. There are 5 factors in the qdec.table.dat file: 1 discrete, 4 continuous variables (covariates). When I tried to perform the multiple correction, Whether I can choose one of two ways (t
