Hello Megan,
I am writing in response to the bug report that you recently submitted regarding the MEGA software. The problem with the captions is definitely a bug that has recently been introduced in MEGA. Unfortunately, MEGA’s session saving system was not well designed in terms of being able to maintain backwards compatibility but we are working on improving the system. The second issue is actually a bug fix. The ability to display scaled bootstrap consensus trees in MEGA has been removed because there are cases where MEGA’s estimation of branch lengths for these trees may not be correct. Although the topology of the consensus trees is correct, they sometimes contain multi-furcations due to the partition frequency cut-offs which are used internally by MEGA for resolving the consensus tree. Estimates of branch lengths in these cases are not correct, as the collapsed partitions have non-zero lengths in reality but they are not statistically resolved (i.e., lack of significance by bootstrap method) and so they are drawn accordingly on the screen.
Best regards,
Glen Stecher |
