Hello fsl users,
I am trying to figure out why I get a discreapancy in the result of fslstats thresholding and
the fslmaths thresholding.
Here is my example:
fslstats image.nii.gz -P 5 -P 95 # Give me the 5 and 95 percentiles of the image (for the non zero voxels)
fslstats image.nii.gz -M -l 6 -u 1220 -M # Use these percentiles to threshold the image and calculate the new -M thresholded value and see how it differs from the non thresholded one.
fslmaths image.nii.gz -thr 6.000000 -uthr 1220.000000 image_thresholded.nii.gz # Do now the same with fslmaths
fslstats image_thresholded -M #Calculate the new -M value
439.634478 # I was expecting that this value would be 473.398263 as fslstats gave.
What am I missing here?
