Abstract

The protocol describes the steps to map HiFi reads to a consensus sequence and retrieve density plots

Steps

Mapping to L1HS/PA2 consensus sequence

1.

A L1HS and L1PA2 consensus sequence was used to create a minimap2 (version 2.24; RRID:SCR_018550) index

#L1 consensus index minimap2 
minimap2 -d L1consensus.mmi L1consensus.fa
```to map FLNC reads (HiFi reads).

2.

The density of mapped reads was visualized in the Integrative Genomics Viewer (IgV) (version 2.12.3; RRID:SCR_011793)

3.

The number of mapped reads in the L1s 5’ UTR was retrieved using samtools view (-c) (version 1.9; RRID:SCR_002105), specifying the first 900 bp of the consensus sequence as the coordinates of interest.
