## Additional Notes: |
|
## Localization can be done and is done before passing the phrases |
|
## to the output. |
|
## This might conflict with special characters, e.g. German Umlaute or |
|
## chinese characters. Do not use such characters in this case. |
|
## If this failed, consider that the sequence and folder names |
|
## are also passed to the output and would fail the same way. |

|
## How this all works: |
|
## Statistics are computed by calling &get_statistics with the sequence, |
|
## resource, and part id to run statistics on. At various places within |
|
## the loops which compute the statistics, as well as before and after |
|
## the entire process, subroutines can be called. The subroutines are |
|
## registered to the following hooks: |
|
## |
|
## hook subroutine inputs |
|
## ---------------------------------------------------------- |
|
## pre $r,$count |
|
## pre_seq $r,$count,$seq |
|
## pre_res $r,$count,$seq,$res |
|
## calc $r,$count,$seq,$res,$data |
|
## post_res $r,$count,$seq,$res |
|
## post_seq $r,$count,$seq |
|
## post $r,$count |
|
## |
|
## abort $r |
|
## |
|
## subroutines will be called in the order in which they are registered. |
