What are the maximum dimensions (i.e., characters x sequences) of a data matrix that PAUP* will read?
The maximum number of sequences (AKA taxa) is 16384. The maximum number of characters (AKA positions or sites) will depend on the type of computer you are using. If your machines uses a 32-bit processor the maximum will be 2^30 (2 raised to the power of 30), whereas machines with 64-bit processors can read a maximum of 2^62 characters.
