Dear Bruce and Freesurfer,

Yes, that is what I am saying! This what appears in the commandprompt when running the command: 

input      cache.th13.abs.sig.cluster.mgh
frame      0
nErode3d   0
nErode2d   0
output     thresholded.mgh
Binarizing based on threshold
min        1.3
max        +infinity
binval        1
binvalnot     0
Found 12485 values in range
Counting number of voxels
Found 12485 voxels in final mask
mri_binarize done

Yet nothing is visible when I open the thresholded surface in tksurfer.


previous:

what was the command line and screen output of the binarization? And are
you saying that pre-binarization you have locations that are above
threshold, but they are set to 0 anyway?
