Dear all,
I am having problems to run GSEA on none affy data and wonder if
someone
could help. I made an annotation library mapping EntrezIDs using
AnnotationDbi and I am able to run KEGG using the custom annotated
package "AB1700sp2.db". But I would like to run trough
GeneSetCollections()and there I need to map probe IDs to EntrezIDs and
then do GeneSetCollections().I tried both make an annotated gene set
or
by using ExpressionSet, but end up with the same type of error.
Any ideas what is wrong?
Best, Lina
