Automatic Error Detection

Automatic error detection denotes all check procedures that may be carried out automatically. There is no certain place in the chain of the post-processing where automatic error checks are most recommended. Whenever possible include automatic checks after each processing step, especially after steps that require manual work.

Here are some possible checks that can be carried out automatically:

An easy way to implement such automatic checks is the usage of a UNIX shell. Most checks are simple UNIX commands or can be easily implemented in a script language like AWK, perl or BASH. If you are using MS platforms7.9, you can use the public domain Cygwin applications that allow you to run a UNIX-like environment on your PC7.10. You may check [11], chapter 5 for a collection of small examples scripts.

In a large data pipeline it may happen that checks are omitted and nobody notices until later. A good way to avoid this is a central log file or database where all checker programs may enter their results together with date and the checked data.
