Goal: Your alignment contains IUPAC ambiguity codes
"r" meaning A or G, and "y" meaning C or T. You want to remove all columns from your alignment
that contain one or more of the ambiguity codes and one or more gaps.
Data: The alignment in the box below contains ambiguity code
"r" column 1, and "y" in column 7. There are also gaps in various columns.
Settings: The tolerance for gaps is set to zero, and in addition
r and y are entered as gap characters in the "gap characters" box. Columns 1, 2,
4, and 7 will be removed when you press the Run button.
