Hi, I am using ChIPQC package for assessing the quality of ChIP-Seq data. However, when I was trying to constructing a
ChIPQCexperiment object, there was always an error:
chipObj = ChIPQC(samples, annotation = "hg19", blacklist = NULL, chromosome = "chr1") FA_1 G3 FA endogenous basal 1 narrow FB_1 G3 FB endogenous basal 1 narrow FC_1 G29 FC endogenous basal 1 narrow Compiling annotation... Error in names(samplelist) <- unique(c(rownames(meta), names(controlist))) : 'names' attribute  must be the same length as the vector 
Did anyone know how to deal with it? Thank you.
