To manually specify a sequence type for the active project:

In most cases, MegAlign Pro can read whether a sequence is DNA, RNA or protein using clues in the sequence itself. In rare cases, you may need to over-ride or manually specify the sequence type.

Choose Edit > Change Sequence Type. After you select the desired sequence type by pressing its button, MegAlign Pro will treat all sequences in the project as being of the specified type.
