The aligner might prefer an alignment without the deletion near the end, which can lead to a false-positive SNP call in addition to missing the deletion.
Starting from a suitable distance measure, we can construct a circular split system from an alignment without significantly prejudicing later tree constructions since the circular split system still represents essentially unfiltered data.
In this option, new sequences are independently added into an alignment, without considering the relationship among new sequences.
If an alignment without indels can be found, we declare the candidate as resulting from a misaligned paralog (see example in Figure 4).
For example, when calculated using an alignment without the variable spacer region, the FtsZ of Aquifex aeolicus, widely considered a deep-branching bacterium, exhibits a similarity to VerFtsZ of only 36.8%, yet shows a similarity of at least 42% to the other representative FtsZs, and other Bacterial FtsZs often display greater similarity to any other Bacterial FtsZs than to VerFtsZ.
(B ) Unrooted Bayesian phylogeny of the 16S rRNA gene for the same taxa as in (A ), based on an alignment of 1,156 bp without indels.
We present an algorithm that automatically selects a partitioning scheme for a given alignment without the need for pre-defined subsets.
On figure 2a, we have a MI plot of an alignment of 256 taxa, without coevolving pairs, with 4 black lines superimposed on it (lets ignore these lines for the moment).
The FMA is quite efficient in space requirement and pattern search time, but it is applicable only for an alignment of strings without gaps.
(A ) Unrooted Bayesian phylogeny of the GH25 muramidase from A. boonei and selected relatives, based on an alignment of 185aa without indels.
(B ) GH2 hydrolase phylogeny based on an alignment of 188aa without indels consisting of top E-value hits to blastp using A. oryzae hydrolase as the query.
