I would like to do a category analysis on our data set.
I had learning vignettes on BioC Subview of Annotation and I found
goProfiles package very close what I think to do.
I have a set of cDNA in fasta format. This cDNA was analysed on one
I would like to group all these cDNA in relation to main function. For example:
100 macromolecular complex
25 ABC Transporter
36 Response to abiotic stress
After have selected the differentially expressed genes, I would like
to group they again and to compare with the previous total list. For
example, from the 100 genes in the group macromolecular complex I get
89 differentially expressed.
Could you tell me if there are some ways for to do this?
I think that I will need:
>From the FASTA get the GO categories
Group in main categories
Subset in accordance with differentially expressed genes
Make the comparison (plot graphs)
I would like to do something like the Figure 2, pag 5, from
This is possible from FASTA?
Thank you very much
