I have attempted to extract the surface and remesh it with ISO2MESH, however, I got error Tetgen command failed. which triggered in surf2mesh.m (line 110-119 as below)

github.com

fangq/iso2mesh/blob/e8fb05c7bfd2eceac4e8775e3fcfc341beba0abd/surf2mesh.m#L110-L119


if(isempty(cmdopt))
  [status, cmdout]=system([' "' mcpath(method,exesuff) '" -A -q1.414a' num2str(maxvol) ' ' moreopt ' "' mwpath('post_vmesh.poly') '"']);
else
  [status, cmdout]=system([' "' mcpath(method,exesuff) '" ' cmdopt ' "' mwpath('post_vmesh.poly') '"']);
end

if(status~=0)
       error('Tetgen command failed:\n%s\n', cmdout);
end

The cmd output is

cmdout =

'Opening C:\Users\Ken\.brainstorm\tmp\post_vmesh.poly.

So, it says out of memory, do you have any idea how to overcome it? thanks
