Hi James

2 answers from me. Personal answer: 4. Practical answer: 5. And 5 is
"Some programs do care about what's present in these columns, so I adapt
and place there whatever is required by the program I am using".

Fred.

PS And what I find really annoying is the atom type specified in columns
77-78, since the information is already present in the same line, as "
CA", " N", "HG" etc. Sometimes I just forget to check what's present in
these 2 columns and I have problems with some programs that refuse to run.
