Hi,

Does anyone know how to get variables in each of PC1, PC2, PC2 in PCA?

Thank you.

Thank you for your reply.

Unfortunately, I still cannot find the way to do it...

I am analyzing a microarray data. I first upload the data for normalization, then, I look at PCA to see how my samples are grouped. Specifically, I'd like to know which probes are involved in the principal component 3, along which my samples separated into 2 groups.

When I open the data correlation result, I do not even see principal component/factor analysis bar...

I appreciate your help!

Try "Principal Components Analysis" under the Pattern Discovery section of the Genomics Starter. This will enable you to look at the PCA results for samples and genes simultaneously.

Best,
