Hi Malcolm,
We have had a problem which may very well be the same as you are
describing. Here is the cause and the solution: The new version of
collection software insist on having a complete set of matrices defined,
even if you will only be using Dye Terminators for example. Otherwise, you
get this error with a cryptic "tag absent " message. The solution is to
create or copy real of fake matrices, following instructions given in the
manual. Once all the required matrices are defined, the program should work
fine.
Like they say, it's not a bug, its a feature!!
Hope this helps
Luc Simon
