Dear experts,
I wish to retrieve a list of human Kegg pathway identifiers for several general biological 'themes' from the Kegg website (such as all environmental signal processing pathway ids) but as I am new to bioinformatics I am unsure how best to do this. I want to go on to use this list of identifiers in the clusterProfiler package in R. I have looked into the available Bioconductor packages such as Kegg.db and KEGGREST but it is not clear to me from the documentation whether I can use them for this purpose and I don't want to invest my time in learning how to use the packages if/they are outdated or there is simpler way to do this.
Any suggestions would be very welcome!
Thanks,
Luanna
I have already worked with a package, called "graphite". It includes kegg pathways and their ids. Of course the goal of this package is not providing name and id of kegg pathways, but you can use it to find id of kegg pathways as well.
Great, thanks for the recommendation, I will give it a try!
Hi, just a quick update. The graphite package certainly looks promising, but I wondered if you could tell me which function you used to extract the pathways? I already have a list of human Kegg pathways, so I am looking to retrieve only those involved in 'environmental information processing' but I couldn't work out how to do that. Thanks again!
'graphite' just includes pathway names and their identifiers.
It does not include any categorization of pathways. So you must determine the name of desired pathways, then you can get their identifiers using graphite package.
