What's the best way of importing gene signature scores (e.g., IFNg signature scores calculated by ssGSEA or gsva) into cbioportal? It'd be great if we can do that and examine the correlation between gene signature scores and other measurements (e.g. mutation status and single-gene expression values).

thanks
Jinfeng

Hi Jinfeng,


Have you already managed to set up cBioPortal locally?

Best,

Sjoerd.

Thanks Sjoerd. I have a related question regarding p-value for signature scores. As current GSVA doesn't generate p-value anymore, can I use some random p-values to fill in when preparing for the signature data?

Regards,
Biao

Hi Biao,

Yes, you can assign all the samples the same p-value. I think you should still be able to use the old strategy for computing the p-values. If I remember correctly, it is just a matter of rerunning the algorithm with perturbed input to see how stable it is with respect to small changes.

Best,

Sjoerd.

Thanks Sjoerd for the explanation.

Appreciate.

You're welcome.

Good luck!
