Fortunately TNT can cope with inapplicable characters...

Exactly how does TNT treat inapplicable characters differently than unknown characters? Shouldn't they be treated the same?

Why not make a stepmatrix. Order "two -- three -- four -- five -- six -- seven", and give the step from each of those to "zero" (or, alternatively, just those from "two" and from "seven" to "zero" -- for example) a cost of 1. PAUP* has no problem with this, plus it spares you the problem of inapplicability with which PAUP* can't cope.

Because step matrices are destroyed everytime I view a matrix in Nexus Data Editor. :)
