Extracting time course from Nifti files?

Hello,

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!

There is no function called y_Read in matlab.

Thank you. I just saw it on a forum and someone used it and apparently it worked. Could you please tell me what should I do instead?
