The TCOFFEE program uses a library of alignments in the construction of the final MSA, and its output MSA is colored according to confidence scores that reflect the agreement between different alignments in the library regarding each aligned residue.
The SVM model was trained with different alignments in the positive and negative training sets, which results in an asymmetric model.
Two types of regions were identified between neighboring blocks: (1) simple indels, where the sequence was cleanly inserted/deleted in one genome relative to the other and (2) 816 cases where sequence was present in both the N2 and Hawaiian genomes but could not be accurately aligned (alignment using various Smith Waterman algorithm implementations revealed different alignments in each case).
We then attempted to compare the different alignments in terms of mean similarity between Gene Ontology (GO) annotations of matched pairs.
Damon can envision a different alignment in 2010, possibly with players like Alex Rodriguez, Jorge Posada and Derek Jeter as well as Damon rotating through the D.H. role.
The roadway between Packwood and Cayuse Pass, added to the state highway system on a different alignment in 1905, was finally completed in 1940, and the White Pass Highway was dedicated on August 12 , 1951 opening a shortcut between southwest Washington and Yakima.
Identifying ab initio conserved regions in different alignments and combining them in a single consensus alignment is more complicated.
For instance, different multiple sequence alignment (MSA) algorithms can produce different alignments, which in turn can influence the inferred phylogenetic reconstruction and thus lead to different conclusions.
Additional properties such as the number of gaps and number of constant sites in the different alignments are shown in Table 2. Estimates of potential sequencing errors in Sminthopsis ESTs indicated an error rate of approximately 0.01% and allelic variation of about 0.02%.
(It's similar to the difference between forming a paper tube by rolling a sheet of paper lengthwise versus on the diagonal: The different alignments of fibers in the paper produce different strength in the resulting tubes). In the case of carbon nanotubes, chirality can determine whether the tubes behave as metals or as semiconductors.
