Hello,
I have a question regarding % thresholding in fslmaths. I am trying to
threshold a file so that that only 50% of the dynamic range of the values
are left in the image, so i am using the following command line:
fslmaths file name -thrP 50 file name
When I look at the resulting image and compare it with the original file, I
notice that the original file thresholded at 20 percent has less voxels than
the 50% thresholded file. Could you explain why this might be happening?
Sincerely,
Anastasia
