The phrase "a number of alignment" is not correct in written English.
It should be "a number of alignments" if referring to multiple instances of alignment.
Example: "The project requires a number of alignments to ensure all teams are on the same page."
Alternatives: "several alignments" or "multiple alignments."
The EST evidence was analyzed using the Program to Assemble Spliced Alignments (PASA) software, which utilizes a number of alignment programs to maximally align transcripts to the genome as introduced by Haas et al. [83].
A number of alignment tools have been developed to align sequencing reads to the human reference genome.
A number of alignment projects have been planned to link English language assessments, domestically produced or internationally recognized, to the CSE.
A number of alignment algorithms have been proposed to solve the MSA problem, such as MULTALIGN [ 5], MULTAL [ 6], PILEUP [ 7] and CLUSTALX [ 8], which provides a graphical interface for CLUSTALW [ 9].
The objective of the general methodology we present here is to compare a number of alignment programs to maximise the number of sequences generated as part of a sequencing project of species A, that are correctly positioned on the already assembled genome of a related species B. A set of paired-end reads must be obtained for species A as part of the genome sequencing project.
A number of alignment-free measures have been proposed in recent years as reported in two comprehensive reviews (Vinga, 2014; Vinga and Almeida, 2003).
An approach based on the generation of a number of alignments by the same algorithm but under different parameter combinations was called "multiple analysis method" by Lee [ 33].
FastTree has been compared favorably to RAxML (Liu et al. 2011) but we bootstrapped a number of alignments using RAxML and found that the BS values from FastTree were inflated as compared with the values from RAxML.
Even after this stringent filtering, there were still a number of alignments that contained only two reference sequences from the CL-Brener genome, but that belonged to these large gene families – mucins, mucin-associated proteins (MASP), trans-sialidase-like proteins, etc.
