The phrase "a representative sequence" is correct and usable in written English.
It can be used in contexts where you want to refer to a sequence that exemplifies or reflects a larger set or category.
Example: "In our study, we selected a representative sequence of data to analyze the overall trends in consumer behavior."
Alternatives: "an illustrative sequence" or "a typical sequence".
Each gene graph also generates a representative sequence that best represents the graph.
A representative sequence was selected randomly for each OTU and classified with the RDP (Ribosomal Database Project) classifier v2.220 using the Silva reference set (119 release)2119
We used RPSBLAST to compare a representative sequence from each ORF cluster against NCBI's Conserved Domains Database to obtain the COG annotation for each ORF with a maximum e-value of 1e−05.
A representative sequence of each OTU was selected for taxonomic assignment using the Greengenes Database (Wang et al. 2007).
A representative sequence of frames following the meniscus movement of dyed water on the air DBD processed microchannel surface containing 300 μm pillar is shown in Figure 6.
CRF is a representative sequence labeling algorithm, which is a discriminative undirected probabilistic graphical model and is suitable for NER tasks.
A representative sequence for each OTU was screened for further annotation with the Green Gene Database DeSantiss et al. 2006) based on RDP3 classifier (Version 2.2) (Wang et al. 2007) algorithm to annotate taxonomic information.
A representative sequence from each OTU was assigned a taxonomic classification based on the Ribosomal Database Project's naïve Bayesian classifier (Wang et al.2007) at an 80% confidence threshold; and all richness and diversity measurements were calculated using the mothur software package based on a random subsampling subset of 1958 sequences to equal the number of reads in the smallest library.
Operational taxonomic units (OTUs) were picked by using de novo OTUs picking protocol with a 97%% identity threshold, then a representative sequence was picked for each OTU and using the RDP (http://rdp.cme.msu.edu) classifier (Wang et al. 2007) to annotate taxonomic information for each representative sequence.
Next, we performed a phylogenetic analysis using a representative sequence of each OTU (total of 54 OTUs) defined by a DOTUR0.03 analysis containing all archaeal sequences (1157).
Sequencing confirmed that all cytosines in the oligonucleotide were converted to thymines after bisulfite treatment; a representative sequence is shown (Figure 4A, lower panel).
