I use iso2mesh to create a mesh on a 3D binary volume. Thanks to vol2mesh and 'cgalmesh' i am able to create a surface and a volume tetrahedral mesh (vol2mesh(vol,512,512,200,opt,maxvol,1,'cgalmesh',);) In the code the following command is used : [node elem,face]=cgalv2m(vol,opt,maxvol); then i am able to plot the tetrahedral volume, and cut it to see the tetrahedral mesh inside : plotmesh(node,elem,'z<150'); (as on the following website : http://morrisvanegas.com/forme/brain.html paragraph ISO2MESH). Finally i want to save it : to only the surface but the entire tetrahedral volume : savestl(node,elem,'file.stl'); Unfortunately it does'nt work, moreover i think that "savestl" save only the surface and doesn't save the volume, is it correct ?.... Can you help me ? to summary i want to save the results of vol2mesh with cgalmesh option in stl format. Thanks a lot in advance !

This three dimensional matrix is binary matrix of image processing. Thank you very much for your reply.(I don't well in english ,I‘m so sorry to that) </comment> <timestamp>: Sat Jun 11 2016 11:12:51 GMT+0800 (中国标准时间)</timestamp> </commblock> <commblock> <author>NIKHIL PILLAI</author> <email>firstname.lastname@example.org</email> <inst>ub</inst> <comment> hi i m using the function "savestl" and have passed nodes, elements and the file name but i am not getting the file in .stl format, its just typpe=file and i am not able to access it. what can be the problem ? thanks </comment> <timestamp>: Thu Nov 27 2014 20:07:38 GMT-0500 (Eastern Standard Time)</timestamp> </commblock> <commblock> <author>octavian lie</author> <email>email@example.com</email> <inst>UT San Antonio</inst> <comment> Dear all, I plan creating surface meshes (for now) for individual 4-layer BEM (skin, skull, CSF , brain), using freesurfer /MNE volumes and surfaces as imput. For the BEM model I use, requirements are: surfaces have to be nonintersecting, closed, limited to 500-5000 vertices each, and delivered in surfacical FS output (such as ?h.pial) or as ASCII file. While I do not have any other constrains except those mentioned for getting boundary meshes such as skin, outer skull, inner skull, I need to use freesurfer pial surfaces (as such or smoothed/eroded 2-3 mm) for the source surface (cortex) for several reasons: consistency with prior experiments, good pial atlases, surface-based registration. It follows that the CSF-gray boundary has to be nonintersecting with this freesurfer pial-derived source surface. I would like to know whether iso2mesh can segment a freesurfer volume 1) creating surface that are nonintersecting, closed, downsampled to 500-5000 vertices each, and delivered in surfacical FS output (such as ?h.pial) or as ASCII file 2) able to create a CSF-gray boundary mesh not intersecting with the freesurfer pial-derived source surface (this boundary mesh can for example be created either by downsampling of the original pial, a smoothed pial surface-such as freesurfer's outer-smoothed pial-, or any other method that preserves the "nonintersection with the source space). I know there are a lot of factors to determine a good vs bad outcome, but I would like to know in principle, Please advise, Octavian Lie, MD PHD UT San Antonio </comment> <timestamp>: Tue Jan 07 2014 22:29:09 GMT-0600 (Central Standard Time)</timestamp> </commblock> <commblock> <author>Medani</author> <email>firstname.lastname@example.org</email> <inst>L2E UPMC Paris</inst> <comment> Hello, thank you for your work, I m à PhD student, in my first year, I will use your programme in my research, so I have some questions about your codes, 1- What is the unit of mesur that you use (centimetres, inches...) 2- How do you numerate the node of the mesh in FEM? Thank you Best regards </comment> <timestamp>: Thu Jan 31 2013 17:25:22 GMT+0100 (Paris, Madrid)</timestamp> </commblock>
