Families found to be missing among the clusters were manually added by gathering sequences from the IPI dataset.
The identification of a unigene set gathering sequences from all genes known to be involved in plant resistance and defense mechanisms, and the construction of a corresponding microarray could constitute a valuable tool to progress in the understanding of plant/pathogens interactions.
I avoided gathering processed sequences in the sequence databases: these include genes predicted from genome annotation pipelines, as well as the vast majority of amino acid sequences which are predicted from nucleotide sequences.
Last week, Celera's president, Dr. J. Craig Venter, said he had finished gathering raw sequence data on the human genome and expected to piece together the millions of fragments into an assembled sequence within three to six weeks.
It makes use of the publicly-available CLUSTALW, PHYML, and BLASTN packages, and automates the manual steps involved: gathering homologous sequences; building and masking multiple sequence alignments; and building and parsing phylogenetic trees.
The gathering threshold of a specific Pfam Markov Model is the sequence-based cutoff at which the Pfam curators "gather" sequences to include in that Markov Model.
By gathering the sequences in a matrix (mathbf {V} = left [{{mathbf {v}_{1}},, ldots,, {mathbf {v}_{B}}}right ] in mathbb {C}^{B times B}), our orthogonality and scaling assumptions lead to V H V=B I B. Arbitrary pilot allocation is considered in this work, with the only requirement of B≥K.
To ensure the quality of the HMMs we added a verification step after gathering new sequences.
Recent advances in sequencing technologies have facilitated the gathering of multilocus sequence data from multiple individuals with extreme efficiency and thereby it has been feasible to acquire such data to explore evolutionary questions on species or population levels, even for non-model species [ 33, 34].
