Dear,

I have a question about the AlphaSim program.
The original voxel of the data was 3.45 X 3.45 X 5+1, and I resampled them to 2X2X2.
In that case, what should be the value of the rmm (cluster connection radius)?
(e.g., AlphaSim –mask “the masked file” –iter 1000 –rmm “2 or 6.1 (larger than 6)”–pthr 0.015 –fwhm 5 –quiet -fast)
And, after deciding the voxel size (e.g., 20) for a corrected p-value, then how can I calculate the volume for the clusters?
Which one is correct between 2X2X2X20 and 3.45X3.45X5X20?
Please let me know.
Thank you.
