Endogenous retrotransposons quantifaction from RNAseq
Has anyone had any experience quantifying retrotransposons in human RNAseq data, eg., LTRs, ERVs, LINE/SINE and Alu1 group RNAs (including SLNRNAs). Is there a custom annotation available to assess these from raw read or bam files? Someone has suggest duskmasker, though when I used it last I don't remember it actually quantifying low complexity regions, but rather simply masking them to either improve specificity in alignment and additional downstream analyses like variant calling.

I've had nice experience with TEToolkit, in particular see my PR to add a TEcount function. That'll give you counts for various levels of TE quantification that you can use in DESeq2 or whatever.
