Normalization and optionally attenuation correction for CTI ECAT 931
transmission or emission sinogram.
Usage: ecatnorm [Options] scnfile nrmfile [atnfile] scnfile2
     Normalization and attenuation correction are removed from a previously
     corrected sinogram.
     Dead-time correction is done (y), or not done (n, default);
     if normalization is to be removed, then this option decides whether
     dead-time correction is removed (y, default), or kept (n).
     Reconstruction programs ecatfbp and ecatmrp correct the data for
     dead-time, therefore it is not done by default here.
