QUESTION

I have no tree. How can I get one ??

 

ANSWER

See ´How to get an initial tree´

 

QUESTION

When I'm using the Phylip tools for building trees, the program skips over the Phylip menu (except in ARB_NT, Phylip Distance Methods). It is, therefore, not possible to use the Phylip options, e.g. to select an outgroup when doing bootstrap analysis.

 

ANSWER

There is a second menu-button in the tree-build sub-menu which starts the original phylip programs with interactive access to all parameters.

 

QUESTION

It would be nice to be able to close a database without having to exit ARB.

 

ANSWER

Sorry, that would be to complicated to program.

 

QUESTION

Finally, do you have a 23S alignment, that I could use? I have tried to build my own, based on the sequences available from RDP. But that's only 34 sequences, and when I align my own 23S sequences against those, the computer runs out of memory. I hope this problem can be solved by putting some more memory in the computer (I currently have 64 mb RAM and I'm going to double that). The shorter 16S sequences causes no problems. Anyway, I would be thankfull if a 23S alignment could be made available.

 

ANSWER

Wolfgang Ludwig has a 23s alignment with 500 Sequences. I will ask him to give it to me and you.

 

QUESTION

When I try to start the aligner V1.0 or V2.0 I get a message: libARBDB.so.2 not found, Aligner failed

 

ANSWER

You are probably using the LINUX operating system and have not installed arb under root account. Please login as root and run the arb_install program again, but don't update the old package.
