Hello,

I have a map of activated clusters that are now ordered size-wise and I want to form a new map with only 1 of them, say #4. How do I do this efficiently. I know I can use 3dmerge -2clip 0 4....and then redo it with 3dmerge 4 10. But I'm wondering if another program would do this more quickly.

Thanks in advance for your help,
Pat
