Hi, I want to do some visualization with FreeSurfer like this command:

`freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:annot=aparc.annot:annot_outline=1:overlay=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/sig.mgh:overlay_threshold=4,5 -viewport 3d`

For example, I did the statistical analysis with my own data, but not with Freesurfer, to visualize my result, i want to use freeview, How can I save my p-value for vertx-wise or ROI-wise into a format .mgh and fit it into Freeview???

Or if any other softwares to visualize the result, I know PySurfer.

Any suggestion will be appreciated

Thanks in advance
