I'm utilizing the Tricycle library found at this link.
I need to predict the cell cycle phase using the project_cycle_space function, which you can review here.
Here's the function syntax:
project_cycle_space( x, exprs_values = "logcounts", altexp = NULL, name = "tricycleEmbedding", ref.m = NULL, gname = NULL, gname.type = c("ENSEMBL", "SYMBOL"), species = c("mouse", "human"), AnnotationDb = NULL )
I'm having difficulty with the ref.m argument, which expects a reference matrix. By default, it's set to mouse, but my data is human. Could you assist me in creating or obtaining a reference matrix for human? I've been struggling with this for quite some time. Thank you.
