Hi Arek,

I've checked that there is data intersection between ensembl, reactome and
our local database like the following:

Ensembl Gene id       Affy_id              Pathway name
ENSG00000047249 221504_s_at Signaling by Insulin receptor
ENSG00000047249 221504_s_at Insulin receptor recycling
ENSG00000047249 221504_s_at HIV Infection
ENSG00000047249 221504_s_at Host Interactions of HIV factors
ENSG00000047249 221504_s_at Nef-mediates down modulation of cell surface
receptors by recruiting them to clathrin adapters
ENSG00000047249 221504_s_at The role of Nef in HIV-1 replication and disease
pathogenesis
ENSG00000047249 221504_s_at Nef Mediated CD4 Down-regulation
ENSG00000047249 221504_s_at Nef Mediated CD8 Down-regulation
ENSG00000047249 221504_s_at Transmembrane transport of small molecules
ENSG00000047249 221504_s_at Iron uptake and transport
ENSG00000047249 221504_s_at Transferrin endocytosis and recycling

The local database contains the affy_id, the ensembl gene id comes from
ensembl and the pathway name comes from reactome. In this case, the problem
should be a software problem I think. Any idea what should be going wrong?

Thanks for your help,

Isaac
