Targets
Could you please assist me with processing RNA-seq data? The reference genome is CP059040. I aim to analyze the data using PCA, a Venn diagram, and KEGG and GO annotation enrichment analysis. The samples are labeled as follows (where 'x' indicates the replicate number): LB-AB-x LB-IJ-x LB-W1-x LB-WT19606-x LB-Y1-x Mac-AB-x Mac-IJ-x Mac-W1-x Mac-WT19606-x Mac-Y1-x -

#Size Factors: These are used to normalize the read counts across different samples. The size factor for a sample accounts for differences in sequencing depth (i.e., the total number of reads) and other technical biases between samples. After normalization with size factors, the counts should be comparable across samples. Size factors are usually calculated in a way that they reflect the median or mean ratio of gene expression levels between samples, assuming that most genes are not differentially expressed. #Dispersion: This refers to the variability or spread of gene expression measurements. In RNA-seq data analysis, each gene has its own dispersion value, which reflects how much the counts for that gene vary between different samples, more than what would be expected just due to the Poisson variation inherent in counting. Dispersion is important for accurately modeling the data and for detecting differentially expressed genes. #So in summary, size factors are specific to samples (used to make counts comparable across samples), and dispersion values are specific to genes (reflecting variability in gene expression). sizeFactors(dds) #NULL # Estimate size factors dds <- estimateSizeFactors(dds) # Estimate dispersions dds <- estimateDispersions(dds) #> sizeFactors(dds) #control_r1 control_r2 HSV.d2_r1 HSV.d2_r2 HSV.d4_r1 HSV.d4_r2 HSV.d6_r1 #2.3282468 2.0251928 1.8036883 1.3767551 0.9341929 1.0911693 0.5454526 #HSV.d6_r2 HSV.d8_r1 HSV.d8_r2 #0.4604461 0.5799834 0.6803681 # (DEBUG) If avgTxLength is Necessary #To simplify the computation and ensure sizeFactors are calculated: assays(dds)$avgTxLength <- NULL dds <- estimateSizeFactors(dds) sizeFactors(dds) #If you want to retain avgTxLength but suspect it is causing issues, you can explicitly instruct DESeq2 to compute size factors without correcting for library size with average transcript lengths: dds <- estimateSizeFactors(dds, controlGenes = NULL, use = FALSE) sizeFactors(dds) # If alone with virus data, the following BUG occured: #Still NULL --> BUG --> using manual calculation method for sizeFactor calculation!

KEGG and GO annotations in non-model organisms

Assign KEGG and GO Terms (see diagram above)
Since your organism is non-model, standard R databases (org.Hs.eg.db, etc.) won’t work. You’ll need to manually retrieve KEGG and GO annotations.
Option 1 (KEGG Terms): EggNog based on orthology and phylogenies
EggNOG-mapper assigns both KEGG Orthology (KO) IDs and GO terms. Install EggNOG-mapper: mamba create -n eggnog_env python=3.8 eggnog-mapper -c conda-forge -c bioconda #eggnog-mapper_2.1.12 mamba activate eggnog_env Run annotation: #diamond makedb --in eggnog6.prots.faa -d eggnog_proteins.dmnd mkdir /home/jhuang/mambaforge/envs/eggnog_env/lib/python3.8/site-packages/data/ download_eggnog_data.py --dbname eggnog.db -y --data_dir /home/jhuang/mambaforge/envs/eggnog_env/lib/python3.8/site-packages/data/ #NOT_WORKING: emapper.py -i CP059040_gene.fasta -o eggnog_dmnd_out --cpu 60 -m diamond[hmmer,mmseqs] --dmnd_db /home/jhuang/REFs/eggnog_data/data/eggnog_proteins.dmnd python ~/Scripts/update_fasta_header.py CP059040_protein_.fasta CP059040_protein.fasta emapper.py -i CP059040_protein.fasta -o eggnog_out --cpu 60 --resume #----> result annotations.tsv: Contains KEGG, GO, and other functional annotations. #----> 470.IX87_14445: * 470 likely refers to the organism or strain (e.g., Acinetobacter baumannii ATCC 19606 or another related strain). * IX87_14445 would refer to a specific gene or protein within that genome. Extract KEGG KO IDs from annotations.emapper.annotations.Option 2 (GO Terms from 'Blast2GO 5 Basic', saved in blast2go_annot.annot): Using Blast/Diamond + Blast2GO_GUI based on sequence alignment + GO mapping
- 'Load protein sequences' (Tags: NONE, generated columns: Nr, SeqName) -->
- Buttons 'blast' (Tags: BLASTED, generated columns: Description, Length, #Hits, e-Value, sim mean),
- Button 'mapping' (Tags: MAPPED, generated columns: #GO, GO IDs, GO Names), "Mapping finished - Please proceed now to annotation."
- Button 'annot' (Tags: ANNOTATED, generated columns: Enzyme Codes, Enzyme Names), "Annotation finished." * Used parameter 'Annotation CutOff': The Blast2GO Annotation Rule seeks to find the most specific GO annotations with a certain level of reliability. An annotation score is calculated for each candidate GO which is composed by the sequence similarity of the Blast Hit, the evidence code of the source GO and the position of the particular GO in the Gene Ontology hierarchy. This annotation score cutoff select the most specific GO term for a given GO branch which lies above this value. * Used parameter 'GO Weight' is a value which is added to Annotation Score of a more general/abstract Gene Ontology term for each of its more specific, original source GO terms. In this case, more general GO terms which summarise many original source terms (those ones directly associated to the Blast Hits) will have a higher Annotation Score.

#https://help.biobam.com/space/BCD/2250407989/Installation #see ~/Scripts/blast2go_pipeline.shOption 3 (GO Terms from 'Blast2GO 5 Basic', saved in blast2go_annot.annot2): Interpro based protein families / domains --> Button interpro * Button 'interpro' (Tags: INTERPRO, generated columns: InterPro IDs, InterPro GO IDs, InterPro GO Names) --> "InterProScan Finished - You can now merge the obtained GO Annotations."
MERGE the results of InterPro GO IDs (Option 3) to GO IDs (Option 2) and generate final GO IDs * Button 'interpro'/'Merge InterProScan GOs to Annotation' --> "Merge (add and validate) all GO terms retrieved via InterProScan to the already existing GO annotation." --> "Finished merging GO terms from InterPro with annotations. Maybe you want to run ANNEX (Annotation Augmentation)." #* Button 'annot'/'ANNEX' --> "ANNEX finished. Maybe you want to do the next step: Enzyme Code Mapping."

- Upload your FASTA file.
- Select an appropriate gene set.
- Download the KO assignments.

Find the Closest KEGG Organism Code (NOT_USED)
Since your species isn't directly in KEGG, use a closely related organism.
- Check available KEGG organisms:
library(clusterProfiler) library(KEGGREST) kegg_organisms <- keggList("organism") Pick the closest relative (e.g., zebrafish "dre" for fish, Arabidopsis "ath" for plants). # Search for Acinetobacter in the list grep("Acinetobacter", kegg_organisms, ignore.case = TRUE, value = TRUE) # Gammaproteobacteria #Extract KO IDs from the eggnog results for "Acinetobacter baumannii strain ATCC 19606"
- Check available KEGG organisms:
-
Find the Closest KEGG Organism for a Non-Model Species
If your organism is not in KEGG, search for the closest relative:
grep("fish", kegg_organisms, ignore.case = TRUE, value = TRUE) # Example searchFor KEGG pathway enrichment in non-model species, use "ko" instead of a species code (the code has been intergrated in the point 4):
kegg_enrich <- enrichKEGG(gene = gene_list, organism = "ko") # "ko" = KEGG Orthology -
