Hi, I am working with some HiChIP data, starting from HiC-Pro outputs. I am running into an error when running HiCDCPlus(gi_list) - see below. I have tried loading the HiC data via the allValidPairs file as well as using the matrix + bed file combination.

Thanks in advance for any help!

# include your problematic code here with any corresponding output 

gi_list_hicpro <- add_hicpro_matrix_counts(
+        gi_list,
+        paste0(hic_mat_dir,"DMSO_rep1_chr_500000_abs.bed"),
+        paste0(hic_mat_dir,"DMSO_rep1_500000.matrix"),
+        add_inter = FALSE)
