Using the simple nearest alignment space termination algorithm, the resulting aligner operates in linear time, requires a small memory footprint, and generates a high quality alignment.
The Python Nearest Alignment Space Termination tool (PyNAST) was used for multiple sequence alignment.
The nearest alignment space termination (NAST) method DeSantis et al. (2006b) used by greengenes uses BLAST (Altschul et al., 1990) to obtain a pairwise alignment between the candidate sequence and the best match in the reference MSA.
In addition, combining the transcriptome with the sequence alignment data, the possible termination site of some PCGs were defined.
Thus, Model 2 predicted two terminators as transcription termination factors, which were validated in analyses of multiple alignment of the corresponding DNA regions.
Upon job termination, the user is directed to the results page, where pairwise alignments are displayed and one can toggle between them, see Figure 2 (right).
We carefully construct a large number of interfacial cells in order to elucidate preferred interfacial terminations and orientations, as well as atom alignment and intermixing across the interface.
Note that keeping a non-zero termination probability is how HMMER achieves local alignments.
Note that in algorithms such as MEME, the algorithm alternates between finding an alignment, and determining the PWM, until the algorithm meets a termination condition and the final PWM is produced.
We did not find such a drop significantly different from the alignment bias pattern ('mappability') of the regions, suggesting that Pol II termination is not generally occurring (Author response image 1B).
A comparative alignment of the MNV signal with other known or suspected termination-reinitiation signals (Figure 8) reveals that Motif 1 is always present and that the stop and start codons of the termination-reinitiation site are in close proximity to each other.
