3dmask_tool error

AFNI Message Board
1

I want to combine my 18 subjects’’ EP data and create new mask.
I made each subject’s BrainMask.nii files using 3dAutoMask
and wrote code for it

3dmask_tool -input subj1_EP_BrainMask.nii
subj2_EP_BrainMask.nii subj3_EP_BrainMask.nii \
…
subj18_EP_BrainMask.nii
-prefix safc_G18
-dilate_result 5 -5

and I got this error massage.

++ no -frac option: defaulting to -union
++ processing 18 input datasets…
++ padding all datasets by 0 (for dilations)
++ frac 0 over 18 volumes gives min count 0
++ voxel limits: 0 clipped, 139406 survived, 171890 were zero

Fatal Signal 11 (SIGSEGV) received

There was a bug at the end of that dilation step,
which is now fixed. New binaries should be
available by about 1 pm EST, if you need them.

Thanks!

Just so you are sure, the binaries were indeed
available as planned. Thanks again for letting me know.
