Dear FreeSurfer Developers,
Hi. I want to manually draw a rectangular ROI on flat map. I tried "PolyLine voxel draw" of ROI edit tool (https://secure-web.cisco.com/1uYpRPHzaQ-b275n3Qt2rqUmDAbInkPLAno41z_mXOvA9D8...).
On the other hand, unfortunately, it seems that it only works in 3d volume space.
So, I tried "Path/Custom FIll" -> pointing 4 vertices of a rectangle -> "Make Closed Path". But this time, the vertices were not connected straight. The lines were zigzag.
Could you tell me how to draw a rectangular ROI with straight lines. Furthermore, if possible, could you explain how zigzag lines form?
Thank you in advance.
Kind Regards, Andy (Junghyun) Kim
