Fbrach error: The tree string could not be parsed correctly! #86

Hi, Thanks for creating this package. I have been troubled by this error. Why is my sample__tree.txt of Dstatistic are all positive and not negative? How to generate negative Dstatistic? How to test all P3P2P1 combinations? I used the same tree file for the Dtrios and DtriosCombine commands and that successfully generated the combined_tree.txt file for the F_branch command. Sub-setting the data and removing the Outgroup didn't make any difference. Any ideas what could be causing this error? Thanks!

$ Dsuite Fbranch newick.txt sample_tree.txt >fbranch.out
