Hello all,
I have searched the forums and found on numerous occasions people attempting to generate roi spheres >5 mm and having difficulties with how the ROI files turn out and how long they take to calculate compared with simple boxes.
I wondered whether there is any consensus/solution to this. I simply want to expand my voxel point of interest to a sphere in a fast and simple way.
My current command is as follows:
fslmaths point.nii -kernel sphere 20 -fmean output -odt float
I have tried changing -fmean to different types of filtering and also applying thresholds but nothing seems to solve the problem. Any advice from the experts?
Thanks,
Joe
