Hi Respected Team,

I am also encoutering the same error given below:

Bam file has 24 contigs Calculating coverage histogram for chr1

Calculating SSD for chr1

Calculating unique positions per strand for chr1

Calculating shift for chr1

300 / 300

Error in names(res) <- *vtmp* : 'names' attribute [10] must be the same length as the vector [2] In addition: Warning message: stop worker failed: wrong args for environment sub assignment

this is my command in R for chipqc:

> library(ChIPQC)
> setwd("/home/admin_gopal@milkyway.allogene.com/CHIP-SEQ/Edited_hg38")
> samples = read.csv("QCexperiment.csv")
> library(TxDb.Hsapiens.UCSC.hg38.knownGene) exampleExp =
> ChIPQC(samples,annotation="hg38",chromosomes=c("chr1","chr2","chr3","chr4","chr5","chr6","chr7","chr8","chr9","chr10","chr11","chr12","chr13","chr14","chr15","chr16","chr17","chr18","chr19","chr20","chr21","chr22","chrX","chrY"),blacklist="hg38-blacklist.v2.bed")

Below is information of environment initialize
