Prototype of the ALE editor

OCCURRENCE

ARB_NT

 

DESCRIPTION

Unfortunately the development of ARB_ALE had been stopped. All what was left was this prototype, which nethertheless offers excellent multiple alignment capabilities. So Niels Larsen and Oliver Strunk decided to plug it into the ARB environment. As ALE is based on emacs it does not use the ARB database directly. Instead it loads all data through a dummy file '/tmp/arb_dummy_user_###.gdbm'. As soon as all data is loaded there are now two copies of the sequences. The sequences in ARB and the sequences in ARB_ALE. So

**** READ THE WARNINGS/BUGS CAREFULLY ****

 

WARNINGS

As soon as you start ARB_ALE, it creates a copy of the selected sequences. That means that you may either change the sequences by ARB_ALE or by ARB, not by both. Therefore, if you have started ARB_ALE, do nothing but sequence editing in ARB_ALE till you have saved and quit ARB_ALE. To save sequence really to disc, you have to send the sequence changes to ARB by selecting 'save' from the file menu and then use ARB to save the ARB-database.

 

NOTES

ARB_ALE needs a lot of computer ressources: You should have

  • at least 48 megabytes of ram
  • a fast computer ( like a 100 megahertz Pentium )

ARB_ALE is not automatically part of the ARB distribution. There is an extra file 'arb_ale.tar.gz' which holds all necessary files which are installed by the arb_install script.

 

BUGS

Everything but sequence editing should be avoided. ARB_ALE is not available for all type of computers. Maybe it is not available for this machine type.
