Hi all,
I have two groups of MRI data. And each group has 13 patients each having Pre and Post. I did normalization, segmentation, bias correction and smoothing using Voxel Based Morphometry toolbox.
Now i want to compare pre and post data of a Group1 paptients using 2 Sample t Test. but I am not getting the option 'Extent threshold' to specify the No.of Voxels. And I want to know whether this depends on 'P value Adjustment'.
So please tell me how I can compare two groups of data after preprocessing.
