Hello,

It looks like 3dStatClust might do what you want, but 3dmerge won't. I say might because I have never used the program myself and it looks like it does not like to read in .1D files (or surface datasets for that matter). I can look into adding this functionality but I cannot get to it for a while longer. Would you still care for it in a couple of weeks?

cheers,
