Hi folks! New user to the program, quick question:

'Error in sequence data file: E at 3 seq 53. Make sure to separate the sequence from its name by 2 or more spaces.'

I've isolated the above sentence to part of the tree.sub program, but I can't figure out what they are referring to.

Is 'E' in reference to a sequence or a population (I have sixteen, going from A-P), and what does the 3 relate to? Happy to upload my input files if helpful.
