Pathway analyses with a transcriptome, which tool shall I use?

Question

[luzglongoria]

Hi,

I have a de novo assembly (a transccriptome) from a Plasmodium organism. I need to do a pathway analysis in order to determine (for instance) the enriched metabolic pathway in the transcriptome. I can compare my transcriptome with a previous genome from Plasmodium that has been published (Plasmodium relictum). the problem is that I am not sure how to do these analyses. I have been reading about some packages in R like ReactomePA but it seems that Plasmodium organisms are not included (https://bioconductor.org/packages/release/bioc/vignettes/ReactomePA/inst/doc/ReactomePA.html).

Thank you so much in advance.

All the best,

Luz
