problem with contrastive principal component analysis (cPCA)

Question

[Raheleh]

Hi all,

I am working with scPCA R package to do contrastive PCA analysis. The dimension of my background dataset is 73 . 1374 and my target dataset is 445 . 13741. (samples in rows and features in columns) This is my script:

cpca_sim <- scPCA(target = df_scaled[ ,-1],
                  background = ortholog_scaled,
                  n_centers = 4,
                  penalties = 0,
                  parallel = T)

I am getting this error

Error in result[[njob]] <- value :    attempt to select less than one element in OneIndex 
Error in serialize(data, node$con, xdr = FALSE) :    error writing to connection

Am I doing sth wrong? Can anyone help me to get rid of this error?

Many thanks!

If you don't get an answer here you might consider posting it over at support.bioconductor.org together with a reproducible data subset, e.g. via dput().
