Hi, i run the code according the https://github.com/yanwu2014/swne, but it get a error.
swne.embedding <- RunSWNE(obj, k = 16, genes.embed = genes.embed)

calculating variance fit ... using gam [1] "0 variable genes to use"
Error in irlba::irlba(t(A), nv = 50, maxit = 500, center = rowMeans(A)) :
max(nu, nv) must be strictly less than min(nrow(A), ncol(A))

so how can i fix it? thanks
