Dear Pedro,
Thank you for your reply.
My core uses FE 10.5.1. All of the columns you mention are present.
As I mentioned in a subsequent posting there are two extra
columns,"start" and "sequence"
which mess up the reading of the data. When they are removed the
normalization works.
So I will not be trying the diagnostics which you suggest below.
I am sending you the column headings off-list.
I can send you data (6 Mb text files) if that would be helpful.
If there is anything I can do to help you improve this important
application please let me know.
Best wishes,
Rich
