how to get siganature gene IDs or symblos?

[Polligator]

I'm just wondering how to get the gene IDs and the sample IDs from a particular cluster on the heatmap, such as the Signature heatmap and the consensus heatmap. is there a function to do that?
Thanks

1. to get the sample ID, you can directly use get_classes() function (https://jokergoo.github.io/cola/reference/get_classes-ConsensusPartition-method.html).

2. to get the gene IDs from the signature analysis, in the data frame returned by get_signatures(), the first column contains the row indices of the original matrix, so you can obtain them by e.g. rownames(expr)[tb$which_row], or in a specific row cluster: rownames(expr)[tb$which_row & tb$km == 2]. https://jokergoo.github.io/cola/reference/get_signatures-ConsensusPartition-method.html

Thanks for your reply, I figured it out.
