Upon investigation, I come to know that SIMBIO which is used for FEM implementation is missing form Fieldtrip package.

(In reply to comment #0) Hi, unfortunately an external program (vgrid), which is only available for linux and mac os x, has to be used for the mesh creation so far. We are currently working on a matlab-implementation of the mesh generation to circumvent this problem. Hopefully, we will be able to provide a first version in a few weeks. Best, Johannes

(In reply to comment #2) Ok. Thanks a lot for your reply. It will be really helpful for me to have the MATLAB code as currently I am stuck in this part. Kindly inform me on munsif.jatoi@gmail.com as soon as you develop the code. Kind Regards, Munsif.

Since Lilla does not work on FieldTrip anymore, I don't think that it makes sense to keep this assigned to her. Also, assigning it back to the team won't speed up its resolution. Since the bug has 'simbio' in its title I suggest to assign it to Simon, who may be the best one to review it, and either follow up on it, or close it.

On the skype meeting today Johannes told that all the whole simbio pipeline is coded in matlab. The only exception is the part where the stiffness matrix is computed. This is done through a MEX-file. I check if they are working on different OS.

(In reply to Simon from comment #5) By checking out external/simbio I realised that also write/read_vista_mesh is a MEX-file
