External Email - Use Caution        

Dear Freesurfer Experts,

I really need your attention and help. Thanks a lot.

We want to create label through the mri_glm-fit-sim cluster results. 

We have found the same topic in 2013 and tried the method you have provided. However, it doesn’t work. If you think it is not the right way, could you give me an example to do it right. I really appreciate your great help. Thanks a lot.

Here is my code:

mri_annotation2label --subject F999  --hemi lh --annotation cache.th20.neg.sig.ocn.annot --labelbase lh.test_label

Here is my error information:
subject = F999
annotation = cache.th20.neg.sig.ocn.annot
hemi = lh
labelbase = lh.test_label
surface   = white
