Gotcha, if you've pulled that ftp link from the
POY 4.0 Tutorials: general commands [1] document then SOME of those files can be found in the code repository [2] with minor name changes. I couldn't find 1Fitch.ss on an older machine we have here, but I would imagine that can be replaced with 30.ss from the repo. All those data-sets have the same taxa names (except for 2.fas), so they can be combined in any way you'd like. Some have partitions, some can be read as prealigned (listed in align_fas and align_aa), et cetera. Sorry for the inconvenience.
