User Inputs
The analysis was performed on the Phylogeny.fr platform and comprised the following steps.


Run mode: full processing mode
Sequences were aligned with MUSCLE (v3.8.31) configured for highest accuracy (MUSCLE with default settings).
Gblocks doc


Min. seq. for flank pos.: 85%
Max. contig. nonconserved pos.: 8
Min. block length: 10
Gaps in final blocks: no
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: 10
-no gap positions were allowed in the final alignment
-all segments with contiguous nonconserved positions bigger than 8 were rejected
-minimum number of sequences for a flank position: 85%
PhyML doc + aLRT


Model: WAG
Statistical test: alrt
Number of categories: 4
Gamma: estimated
Invariable sites: estimated
Remove gaps: enabled
The phylogenetic tree was reconstructed using the maximum likelihood method implemented in the PhyML program (v3.1/3.0 aLRT). The WAG substitution model was selected assuming an estimated proportion of invariant sites (of 0.000) and 4 gamma-distributed rate categories to account for rate heterogeneity across sites. The gamma shape parameter was estimated directly from the data (gamma=0.845). Reliability for internal branch was assessed using the aLRT test (SH-Like).
