我正在嘗試編寫代碼來(lái)解析 Gene Ontology (GO) OBO 文件并將 go 術(shù)語(yǔ) ID（例如 GO:0003824）推送到樹(shù)狀嵌套字典中。OBO 文件中的層次結(jié)構(gòu)用“is_a”標(biāo)識(shí)符表示，用于標(biāo)記每個(gè) GO 術(shù)語(yǔ)的每個(gè)父級(jí)。一個(gè) GO 術(shù)語(yǔ)可能有多個(gè)父級(jí)，而層次結(jié)構(gòu)中最高的 Go 術(shù)語(yǔ)沒(méi)有父級(jí)。GO OBO 文件的一個(gè)小例子如下所示：[Term]id: GO:0003674name: molecular_functionnamespace: molecular_functionalt_id: GO:0005554def: "A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. These actions are described from two distinct but related perspectives: (1) biochemical activity, and (2) role as a component in a larger system/process." [GOC:pdt]comment: Note that, in addition to forming the root of the molecular function ontology, this term is recommended for use for the annotation of gene products whose molecular function is unknown. When this term is used for annotation, it indicates that no information was available about the molecular function of the gene product annotated as of the date the annotation was made; the evidence code "no data" (ND), is used to indicate this. Despite its name, this is not a type of 'function' in the sense typically defined by upper ontologies such as Basic Formal Ontology (BFO). It is instead a BFO:process carried out by a single gene product or complex.subset: goslim_aspergillussubset: goslim_candidasubset: goslim_chemblsubset: goslim_genericsubset: goslim_metagenomicssubset: goslim_pirsubset: goslim_plantsubset: goslim_yeastsynonym: "molecular function" EXACT []
