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?

Dear Bruce and Freesufers,
I get the following message:
surfer: Interpreting overlay volume/media/EHD/ALLA_FREESUFER_PROCESSING_TIDIS_NOMAS_AD/qdec/lh.kvot_gender.glm dir/Gend/thresholded.mgh as encoded scalar volume.
the two volumes I tried to convert:

Although both these overlays have significant areas - nothing appears on the binarized version after the conversion
