Hi Dave,

I think you should do your task in several steps.
First import you gene/protein list using Global Search bar at the top right corner, through Upload File; there is Choose Organism option.
Then from the Search Results panel, chosing the your genes/proteins by right clicking run BuildPathwaysWizard to construct a network over your gene/protein list. You can use different filters on the types on edges (interactions; co-expression; etc) you want.
After you constructed the network, open your gene expression data separately; and use "color the network nodes" from the microarray toolbar.
To construct co-expression network, use "Construct co-expression network" button on the microarray toolbar. The edges are strength is proportional to Pearson correlation.
Then you can merge the interaction and co-expression networks.

Is that what you need?

Hi,

thanks for the answer. yes, I could construct the co-expression network.
If I merge networks how can I specify the edges by types?
I want the physical interaction edges be of the one style and co-expression edge
with the edge color and thickness corresponding to positive/negative correlation and the strength of co-expression. Do you have some visual mapper of node/edges properties?

Thanks.

Also, how can I mine your integrated database for public gene expression data (for ex. GEO) when constructing the networks?

The issue is solved.
