Could you please help me? I have a .nii file from an MRI data set (x,y, nr of slices,time points). I would like to extract the intensity of the voxels of each time point, plot them, and fit a polynomial. Could you please tell me how to extract the time points and to plot them? I tried: [Data Header]= y_Read('trial.nii') but i had an undefined function error and I don't know where to find it.
Any suggestions would be helpful. Thank you very much!
