I haven’t seen anyone answer this on the list, but I hope someone replied off-list.

 

If this a human subject, you might be able to convert the freesurfer output to something Connectome Workbench can read:

 

MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://github.com/Washington-University/HCPpipelines/blob/master/PostFreeSurfer/scripts/FreeSurfer2CaretConvertAndRegisterNonlinear.sh

 

Then you can get your hands on a 32k_fs_LR flat map and draw on that.

You can then view the borders on midthickness, inflated, or flat as desired.

 

Don’t know about the zig zag thing.

Dear FreeSurfer Developers,

 

Hi. I want to manually draw a rectangular ROI on flat map. I tried "PolyLine voxel draw" of ROI edit tool (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FreeviewGuide/FreeviewTools/RoiEdit).

 

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
