Recently, I used XHMM to call CNV based on WES data. All the parameters were set to as the same as the XHMM workflow showed in the documentation xhmm_tutorial, and also the same as the filename. But I got an R error as follow when I drew CNV plots. Similarity, I even used the demo data set RUN from the documentation.

library(xhmmScripts)

PLOT_PATH="/Users/CJ/Desktop/RUN/"
OB_PREFICES="/Users/CJ/Desktop/RUN/DATA"
OB_TARGETS_TO_GENES="/Users/CJ/Desktop/RUN/annotated_targets.refseq.loci"
SAMPLE_FEATURES=NULL

XHMM_plots(PLOT_PATH, JOB_PREFICES, JOB_TARGETS_TO_GENES, SAMPLE_FEATURES)

Loading data from '/Users/CJ/Desktop/RUN/DATA' XHMM run...

How do I draw the plots with the XHMM results? By the way, I used the hg19 for the reference genome. The chromosome ID begins with "chr". Thanks!
