Hi Tsjerk, Coffee is always magical, I tell you. Just a sniff in the air and it makes things clear.
So, 1/n sum is the mass weighted ness? And x1 to zn spans from 1 to 1992? By any chance we don't obtain a file I. Which the first column wud have alpha atom one second column would have 2nd aloha atom n third would have correlation between them?
