vmpreturnvec.m

vmp is the file generate from Brainvoyager which can link vtc file and the 3D image. This toolbox he

function vmpVec = vmpReturnVec(path, vmp);
% syntax: vmpVec = returnVMPvec(path, vmp)
% 
% this func returns the vmpMat of the map [path vmp '.vmp']
% in a vector form (which is vmpMat read in the order: 
% for z=1:slices
%   for y=1:rows
