hicPCA flip signs with rna-seq?

[Naveen-Ahuja]

Hi,

I would like to know if it makes sense to use rnaseq bigwig file in hicpca to flip the signs. For example, choose extra track type --> Histone Mark --> Histone Mark type=active. Would this be appropriate as there isn't an explicit rnaseq option, only histone mark and gene density?

Thank you

Just following up using a bigwig file gives this error on the hicexplorer web:
