STEP 18 error

[lifan2022]

Hello, I encountered an error when using Infercnv

My code is :

options("Seurat.object.assay.version" = "v3")
options(scipen = 100)
infercnv_obj = infercnv::run(infercnv_obj,
cutoff=0.1,
out_dir='~/shengjing/result/1/CNV',
cluster_by_groups=FALSE,
analysis_mode="subclusters",
denoise=TRUE,
HMM=TRUE)
INFO [2024-08-07 18:29:08]

My error is :

STEP 18: Run Bayesian Network Model on HMM predicted CNVs

In addition: Warning message:

My version of infercnv is 1.16.0

I don't know how to deal with this problem, I hope you can help me.
