| Summary | 0001023: inconsistent distance estimates | ||||||||
| Description | Dear Professor Kumar, I estimated within group mean distance for a protein alignment using Mega 5 and Mega X (version 10.0.5), respectively. However, I obtained different estimates (huge difference). When I estimated between group mean distance, I found the same problem. I don't know why different versions give different estimates and which version is more reliable. Hope to hear from you soon. Thank you for your help. All the best, Weifeng | ||||||||

Hi Weifeng, I am writing in response to the bug report you recently submitted regarding the MEGA Software. I am not able to reproduce any difference in calculating within or between group mean distances when using MEGA5 and MEGAX. No matter what data and settings I use, I always get exactly the same results. Can you send me the data used as well as screen shots of the Analysis Preferences used so that I can reproduce the issue? -- Best regards, Glen Stecher Institute for Genomics and Evolutionary Medicine igem.temple.edu |

Hi Weifeng, I get the same results between MEGA5 and MEGAX with your data. Please make sure that you are using the same options and data subset between the different versions of MEGA.
