vtc2vmp.m

VTC file is the file format of the Brainvoyager. The FMRI matchine scan human s brain and get the vt

function vtc2vmp(path, vtc, output);
% syntax: vtc2vmp(path, vtc, output);
% this func gets a vtc with 1 value at each voxel (1 point TC), and make a
% VMP from it (actually write this value (normalized between 0-1) in a
% correlation map format)
