Usage: CreateIcosahedron [-rad r] [-rd recDepth] [-ld linDepth]
[-ctr ctr] [-prefix fout] [-help]
- -rad r: size of icosahedron. (optional, default 100)
- The edge length l = 4 r / sqrt(10+2sqrt(5)) The area a = 5 sqrt(3) l^2 The volume v = 5/12 (3+sqrt(5)) l^3
- -rd recDepth: recursive (binary) tesselation depth for icosahedron
- (optional, default:3) (recommended to approximate number of nodes in brain: 6 let rd2 = 2 * recDepth Nvert = 2 + 10 * 2^rd2 Ntri = 20 * 2^rd2 Nedge = 30 * 2^rd2
- -ld linDepth: number of edge divides for linear icosahedron tesselation
- (optional, default uses binary tesselation). Nvert = 2 + 10 * linDepth^2 Ntri = 20 * linDepth^2 Nedge = 30 * linDepth^2
- -min_nodes MIN_NODES: Automatically select the -ld value which produces an
- icosahedron of at least MIN_NODES nodes.
- -nums\ : output the number of nodes (vertices), triangles, edges,
- total volume and total area then quit
-nums_quiet: same as -nums but less verbose. For the machine in you.
- -ctr ctr: coordinates of center of icosahedron.
- (optional, default 0,0,0)
-tosphere: project nodes to sphere.
- -prefix fout: prefix for output files.
- (optional, default CreateIco)
- The surface is written out in FreeSurfer’s .asc format by default. To change that, include a valid extension to the prefix such as: fout.gii
