![]() ![]() This approach is typically accomplished by submitting separate searches to multiple disparate web servers and comparing results by clicking between tabs then saving the final annotation in a text file or spreadsheet. There are many examples in the literature which use this approach to improve upon previous annotations. #Clc sequence viewer add annotation manual#Optimal manual functional annotation involves using an ensemble approach, where multiple tools and databases are used and results from each are compared and contrasted. While these automated tools provide convenience, manual curation is needed for more accurate and detailed annotations. The previously described annotation use cases require detailed and accurate annotations. There have been several efforts to completely automate the process of microbial genome annotation Systems such as RAST (Rapid Annotation using Subsystems Technology), Prokka, and the Prokaryotic Genome Annotation Pipeline (PGAP) can predict gene locations and provide a functional annotation with the click of a button. For example, human genome annotation may be used for discovering disease-causing variants, prokaryotic annotation for discovering genes responsible for pathogenicity or antibiotic resistance, and viral genome annotation for discovering potential targets for therapeutics. A fundamental use of annotation is to discover and characterize genes of interest. After gene calling, a descriptive label and metadata are provided for each predicted gene in a process called functional annotation. #Clc sequence viewer add annotation software#Typically, this is performed using automated software tools such as Glimmer, GeneMark, or Prodigal which use statistical modelling to predict the presence and location of each gene. The location of functional regions is determined in a process called gene calling. Genome annotation is the process of locating and labelling functional regions within a genome. MAS is ideal for team-based annotation projects because it facilitates collaboration. The structure that MAS provides can improve project organization and reduce annotation errors. MAS enhances the ability of users to generate, interpret, and compare results from multiple tools. MAS streamlines and provides structure to manual functional annotation projects. ![]() MAS can take advantage of high-performance computing (HPC) clusters by interfacing with SGE or SLURM and data can be exported from MAS in a variety of formats (FASTA, GenBank, GFF, and excel). MAS was designed to accept connections over the local area network (LAN) of a lab or organization so multiple users can access it simultaneously. MAS provides users with pertinent information through a simple point and click interface to execute and visualize results for multiple homology search tools (blastp, rpsblast, and HHsearch) against multiple databases (Swiss-Prot, nr, CDD, PDB, and an internally generated database). MAS allows users to upload unannotated genomes, provides an interface to edit and upload annotations, tracks annotation history and progress, and saves data to a relational database. We created Manual Annotation Studio (MAS) to improve the efficiency of the process of manual functional annotation prokaryotic and viral genomes. ![]() Manual annotation efforts are time-consuming and complex however, software can help reduce these drawbacks. Manual curation can produce higher quality genome annotations than fully automated methods. Functional genome annotation is the process of labelling functional genomic regions with descriptive information. ![]()
