About the mask for Alphasim correction

Dear professor Yan,

I have a question about the mask of Alphasim correction in voxel-wise functional connectivity. Specifically, to test the link between functional connectivity of the vmPFC and  procrastination, I performed a correlation analysis between functional connectivity maps from the vmPFC and scores of procrastination, using result map from one-sample t-test of individuals’ functional connectivity maps of vmPFC as mask. In the following Alphasim correction, Can I use the same result map from one-sample t-tests as mask.

Thank you for your explanation.

GOOD LUCK.

Zhang
