Description of Homologous Genes in TGT


Based on the algorithm of GeneTribe, homologous genes are divided into four types: RBH (Reciprocal Best Hit), SBH (Single-side Best Hit), singleton, and 1-to-many (all putative homologous genes). The description of homologous genes is shown in the figure. The black blocks represent genes. The lines represent homologous relationships.

Definition of the Distance in Collinearity Plot


The Distance, which is used to determine total number of genes on the chromosome, refers to the number of flanking genes.


In addition, TGT provides various functions for visualization, saving format (PDF, PNG and CSV formats), and Links to external databases.

All tools have option numbers to indicate the order of input, such as 1,2, and 3.1.

Layouts of all modules are divided into two parts: the input area and the output area.

Only the longest transcripts that represent the genes are used and showed.
