Okay, let me try to work through this. The user is asking about how the pathway enrichment analysis was conducted in the provided article. They want to know specific details like the tool used, version, gene set library, background genes, statistical test, and FDR correction. First, I need to look through the text for mentions of enrichment analysis. The article is about a database called croFGD and includes sections like Methods, Results, Discussion, etc. Since the user mentioned the Methods section is key, but other sections might have info too. Starting with the Methods section. Wait, actually, looking at the text provided, the user pasted a part that seems to be the Results and Discussion, not the Methods. But maybe the Methods were not included here. Let me check the text again. Looking at the sections given, the user provided the Results and Discussion parts. The question is about the Methods, but since the user says "carefully examine how pathway enrichment analysis was conducted in this scientific article. Focus on the Methods section, but information can also be found in other sections." However, the text provided doesn't have a Methods section. Hmm, that complicates things. But maybe the answer is embedded in the Results/Discussion parts. In the Results sections, there are mentions of enrichment analysis. For example, in the part about the CPR gene's analysis: "co-expression network analysis and module enrichment analysis can be benefit to predicting gene function effectively and refining gene annotation." Also, in the CPR section, they mention "module enrichment analysis" and "GO terms". Looking at the CPR example: "the integration of co-expression network analysis and module enrichment analysis can be benefit to predicting gene function effectively". Then in the CPR global network, they mention "module enrichment analysis" which might refer to GO or KEGG. Another part: "Functional module annotation and integrated method could improve and refine gene function annotation from diverse perspectives". They mention "annotation of these functional modules covered vindoline and vinblastine biosynthesis, jasmonic acid biosynthesis, hormone response and pathogen resistance, etc." So maybe they used GO and/or KEGG terms for the pathway enrichment. Looking at the references, there's a mention of "KEGG pathway and GO terms, needs to be integrated". But the user is asking about what was actually used in the article. The key part is in the CPR analysis: "module enrichment analysis". The authors also mention "GO terms" in the Discussion. For example, "KEGG pathway and GO terms, needs to be integrated" suggests that they used GO and KEGG. However, the exact tool isn't named here. Wait, in the CPR part, they mention "module enrichment analysis". The term "enrichment analysis" is used in the context of GO terms. The authors also mention "GO: molecular function, cellular component, and biological process" in the database description. Looking at the Data Availability section, they mention that data is from NCBI SRA. The Methods might not be here, but the article's text says: "the integration of co-expression network analysis and module enrichment analysis can be benefit to predicting gene function effectively". Wait, in the CPR section, they mention "module enrichment analysis" which could be using GO and KEGG. The authors also mention that "annotation of these functional modules covered vindoline and vinblastine biosynthesis, jasmonic acid biosynthesis, hormone response and pathogen resistance, etc." So these are pathways, possibly from KEGG or similar databases. The question is about the tool used. The user is asking for the tool name. The article might not explicitly state the tool. For example, in the text, they mention "GO terms" but not the software. Common tools for GO enrichment are DAVID, GOseq, clusterProfiler, or others. But the article doesn't name a specific tool. Looking at the references provided (though the references are listed but not fully included here), perhaps in the references there is a mention. For example, the authors cite "Chen et al., 2013" and "Coneva et al., 2014", but without seeing those references, can't tell. Since the user provided the text up to the references but the actual references are not included here, we can't check that. The question is about the tool used. Since the text doesn't mention any specific software tool for the pathway enrichment analysis, the answer might be that it's not described. Alternatively, maybe they used a standard method with GO, but without naming the tool. Another part: "the annotation of these functional modules covered vindoline and vinblastine biosynthesis, jasmonic acid biosynthesis, hormone response and pathogen resistance, etc." This suggests they used KEGG pathways as well as GO. But the exact tool isn't mentioned. Looking at the Supplementary Material mentions: "Supplementary Table S6" which might have more details, but since the user hasn't provided that, we can't check. The question is about pathway enrichment analysis. The article mentions "GO terms" and "KEGG pathway" in the limitations section, but in the methods (as described in the text provided), the tool isn't specified. In the CPR example, they mention "module enrichment analysis". Maybe they used a custom approach or a common tool like GO enrichment using hypergeometric test, but without stating the tool. The user's question is about the tool used. Since the text provided doesn't explicitly name a tool (e.g., DAVID, clusterProfiler, etc.), the answer would be that it's not described. Looking again at the text: "Functional module annotation and integrated method could improve and refine gene function annotation..." The term 'module enrichment analysis' might be part of the co-expression network analysis. The authors might have used tools like WGCNA (Weighted Gene Co-expression Network Analysis) which includes module enrichment, but that's an assumption. However, the article doesn't mention WGCNA or any specific software. The answer to the first question is: The tool used is not described in the provided text. Second question: version? If the tool isn't mentioned, then no. Third: gene set library: they mention GO terms and KEGG pathways (from the limitations section where they say "KEGG pathway and GO terms, needs to be integrated"). So possibly GO and KEGG were used as gene set libraries. Fourth: background gene list? The article doesn't specify if a background list was used. Maybe the entire genome or the co-expression network genes, but not stated. Fifth: statistical test. Since enrichment usually uses hypergeometric or Fisher's exact test, but they didn't mention it. So not described. Sixth: FDR correction? They might have used FDR, but again, the text doesn't say. So compiling the answers based on the provided text: 1. Tool: Not described. 2. Version: Not applicable, since tool isn't mentioned. 3. Gene set library: GO and KEGG (inferred from context). 4. Background gene list: Not described. 5. Statistical test: Not described. 6. FDR correction: Not described. Wait, but in the CPR part, they mention "module enrichment analysis". Maybe in module analysis, they used some standard tests. Alternatively, in the Methods (which we don't have here), they might have mentioned it. Since the user only provided the Results/Discussion parts, perhaps in the Methods they didn't explain. Since the user's text does not include the Methods section, which is where this info is usually found, but the user says "focus on the Methods section, but info can be found elsewhere". The article's text mentions in the Results that "module enrichment analysis" was done, but no details on tool or stats. The Discussion mentions "GO terms" and "KEGG pathway", so the gene sets are GO and KEGG. But the exact tool isn't named. Therefore, the answers are as above. 1. **What tool was used for pathway enrichment analysis?** Not described. The article does not explicitly mention the specific tool used for pathway enrichment analysis. 2. **Was a tool version number provided?** Not applicable, since the tool is not specified. 3. **What gene set library was queried (e.g., GO, KEGG, Reactome, or other)?** The analysis likely used **Gene Ontology (GO)** and **KEGG pathways**, as these terms are mentioned in the context of functional annotation (e.g., "annotation of these functional modules covered ... jasmonic acid biosynthesis" and references to "KEGG pathway and GO terms"). 4. **Was a background gene list defined for pathway enrichment analysis?** Not described. The article does not specify whether a background gene list was used or how it was defined. 5. **What statistical test was used for enrichment analysis?** Not described. The statistical test (e.g., hypergeometric test, Fisher's exact test) is not mentioned. 6. **Was false discovery rate (FDR) correction used to control the number of false positives in the pathway enrichment analysis?** Not described. The article does not mention FDR correction or any multiple testing adjustment method.
