Outputs: Settings: Min. seq. for flank pos.: 55% Max. contig. nonconserved pos.: 8 Min. block length: 5 Gaps in final blocks: half |
After alignment, ambiguous regions (i.e. containing gaps and/or poorly aligned) were removed with Gblocks (v0.91b) using the following parameters: -minimum length of a block after gap cleaning: 5 -positions with a gap in less than 50% of the sequences were selected in the final alignment if they were within an appropriate block -all segments with contiguous nonconserved positions bigger than 8 were rejected -minimum number of sequences for a flank position: 55% |
