Dear,

I have one more question about the AlphaSim program.
At first, I used p<.005 of the voxel-wise threshold and 9 voxels for the P<.05 of the cluster-wise threshold based on the AlphaSim.
Our experimental manipulation was based on the psychological abstract concepts and, in turn, the strength of the changed brain activations was not high enough in some regions.
In this situation, in the same cluster-wise threshold (p<.05), can I use a lower voxel-wise threshold (p<.015) and a higher spatial threshold (e.g., 20) based on the AlphaSim?
If it's possible, are there any articles that I can use as a reference?
Thank you ahead.
