The relevance to TreeTapper is how and whether to record information about how programs perform with large trees. The first question is whether it's meaningful. For a simple program with one function, it's possible that it always fails if trees are over N taxa in size or if likelihoods get below X. But for complex programs like Mesquite, they might fail for some trees for some methods but work for others, so just storing a single number might be misleading. A second issue is that gathering the data might be difficult: for a typical user, deciding whether a program crashed with a tree with N taxa due to the tree size or some other bug will be hard. It also seems unreasonable to expect people to report to TreeTapper every time a program works or fails for them and under what conditions (I wouldn't make the time to do so). On the other hand, it would be helpful to users to know that a certain program just can't work with trees of a certain size and helpful for developers to know which programs need tweaking for large trees. I guess for now I won't have a separate field for this and will just rely on user comments on each program page, but let me know if you have any suggestions.
