Hi everyone,

I am having trouble running heuristic searches with NT algorithms using a matrix with landmark characters.

My searches keep crashing at random moments with the message "internal error in TBR calculation", which halts the entire process.

I found that removing certain NT options (such as tree fusing) and including the command lmark errmarg 0.00001 in my .run script made the analyses run for a significantly longer time. However, I don't know if altering this error margin is recommended, and the search still eventually crashes with the same internal error.

Could anyone shed some light on how to bypass this problem (even in the middle of the World Cup)?

Abraço, Pedro Costa

(P.S.: My matrix has 91 taxa and 57 characters: 6 2D landmarks, 22 continuous linear, and the rest discrete. I am running TNT v. 1.6 via command line on my University's Linux cluster)
