I have written a very simple program which, unlike MEGA, is free and is ftpable
from zoo.toronto.edu/pub called "tease.exe"
It will strip out all uninformative characters from an data set of anysize.
One ceveat is that your data need to be in Hennig86 format.
That is: A=0, C=1, G=2, T=3, - = ? or -.
And the data must be arranged as follows:
one 0113201232 ... <base 1200>
two 0113201232 ... <base 1200>
thr 0113201232 ... <base 1200>
fou 0113201232 ... <base 1200>
fiv 0113201232 ... <base 1200>
If you have PAUP, you can simply take your file and export for Hennig86.
The application is for DOS.
It works much faster at removing uninformative than MacClade does for
It only removes characters that are uninformative under ALL optimization
criteria, tells you which characters were removed and creates a new file
with the informative characters only.
