Hello, I am new in ChIP-seq analysis. I tried to use ChIPQC make a quality control of my samples but something went wrong.
library(ChIPQC)
library(BiocParallel)
setwd("/mnt/data/home/tycloud/CUT_TAG")
samples=read.csv("GW_S3_SampleSheet.csv")
inputExp <- ChIPQC(samples,annotation = "hg19",chromosomes=1)
When I chose one chromosome to investigate, everything went well. However, when the number of chromosomes increased, some error appeared (only in BiocParallel ).
inputExp <- ChIPQC(samples,annotation = "hg19",chromosomes=c(1,2))
##Error: BiocParallel errors
##0 remote errors, element index:
##8 unevaluated and other errors
##first remote error:
I have tried method like adding "BPPARAM <- SerialParam()", but it didn't work.
BPPARAM <- SerialParam()
inputExp <- ChIPQC(samples,annotation = "hg19",chromosomes=c(1,2),BPPARAM = BPPARAM)
What do unevaluated errors exactly stand for? and How to fix them? Thank you all in advance for your help!

Playing video games online at Slope is one of the ways that we get to show off our muscles to all of our new friends that we have made all across the world. It is possible to become addicted to it, and I believe that parents have a lot of responsibility in making sure that things go more smoothly in this regard.
