Just out of curiosity, does anyone have empirical experience with
how many sequences can be aligned with the current version of Clustal (1.8)?
I was surprised that I could do something like 69 sequences without
much problem on my Mac G3 (Clustal X, rDNA sequences about 1.8 kb average,
default settings). Now I am wondering how many I could do if I waited longer
or installed Clustal W on a Unix box. I am suspecting that Clustal is
about as fast as any, reasonably effective, program, but please
enlighten me if I am wrong.
