| Summary | 0000441: MEGA-CC is very slow when using Bootstrap | ||||||||||||
| Description | When doing Phylogeny Reconstruction, MEGA-CC is very slow when using Bootstrap in Neighbor-joining (~20s). The GUI version on MEGA is very fast (<1s) An example data containing alignments of four DNA sequences is attached. The result is: No. Bootstrap Running time(s) None 0.046 50 2.578 100 5.114 200 10.179 500 25.374 | ||||||||||||
| Steps To Reproduce | Platform: CentOS 6.9, x86_64 Data: see attached file MAO: see below =========== infer_NJ_nucleotide.mao ============= ; Please do not edit this file! If this file is modified, results are unpredictable. ; Instead of modifying this file, simply create a new MEGA Analysis Options file by using the MEGA Prototyper.
