# Tutorial: Proteome Comparison Service
## Overview
This set of short videos provides a step-by-step demonstration of using the PATRIC Proteome Comparison Service to identify insertions and deletions in up to nine target genomes that are compared with one reference, which can be a researcher’s private genome in PATRIC, a genome that has been annotated outside PATRIC, any of the publicly available genomes in PATRIC, or a set of proteins that you have saved in PATRIC as a feature group.

2. [Selecting a reference genome (3:05)](#proteome2)
3. [Using a feature group or FASTA file as input (5:20)](#proteome3)
4. [Using a FASTA file as the reference (3:38)](#proteome4)
5. [Using a feature group as the reference (2:04)](#proteome5)
6. [Selecting the genomes to use for the comparison (5:57)](#proteome6)
7. [3 flavors of reference genomes (5:38)](#proteome7)
8. [Reviewing the output job results (22:54)](#proteome8)
