External Email - Use Caution
Hi Bruce,
Thank you very much for your kind reply. We have dozens of ROIs and hundreds of individuals, we need to draw the mask for each individual. May I know If I could do it in command lines? If it is applicable, which commands/functions should I refer to?
In addition, whether it is possible to use the index (16k+ for each surface) of this peak vertex in a annotation file to draw the mask? I am not clear how the index of each vertex ranked in a surface, could I found the index-vector of all the vertices in the circle mask centred the peak vertex? If circle is not applicable, how about square?
Best regards,
Lizhi

Hi Lizhi
the easiest way to approximate this is to generate a label that is just the peak vertex, then use the label editing tools in the current dev version of freeview to dilate it 4-5 times.
cheers Bruce

Now I would like to find the peak vertex showed significant group effect
in a given ROI (e.g. left
insula), then draw a 5-mm-radius circle mask centred this peak point.
May I know whether it is
applicable and how should I do it with command line? Any suggestions
would be much appreciated.
Best regards,
Lizhi
