how do normalization for transcript length

Question

[lkianmehr]

I have got transcript quantification by Salmon, then import them to tximport and got transcript count, length and abundances. now I would like to make a transcript coverage graph in terms of normalized counts on normalized position along transcript. I have normalized counts by DESeq2 but I don't know how do normalization for transcript length. Does anybody have any idea?

thanks
