in reply to mapping data between files

It looks like you have a few steps to do to solve this.

The problem seems to be ill defined. For example, you refer to "entry number 1 but not all". Do you mean "entry number ONE but not all"? What happens in the case of "not all"? Is there a problem domain into which this problem fits? If so, there may be a module that reads these types of files already.

Update: This could also be afternoon fog. Is the information on the lines like >ONE indicating the name of a file to read?

    Thanks for your quick response! >ONE etc does indeed indicate the name of a file to read

    For example - the 'ONE' co-ordinate file corresponds to the sequence IRLA in the sequence file

    So ... in the above test case you have one sequence file but 3 corresponding co-ordinate files
