The problem is that ["-p blastn"] means that there's only one argument, while ["-p", "blastn"] means what you want. In a Unix shell, what you're doing is the same as 'blastn "-p blastn"', which is clearly wrong. Why are things like this? Well, imagine that you wanted to pass a file as argument, and that file had a space in its name. Having a list of arguments leaves you unconcerned about these subtleties. -- Felipe.
