Dear SPMers, Is there an SPM or Matlab procedere to reconvert several 3D Studies (all in Analyze Format) from the same Patient to one large 4D Studie ? Surley this seems trivial for Matlbab programmers, but before I'm forced to write a routine on my own I want to ask you. Maby this Problem is solved from someone else. Thanks in advance, Florian [log in to unmask]
