Now that we have launched FragPipe, we need to configure the settings prior to running the analysis. Therefore, we have provided some guiding questions to help you set up the settings in FragPipe:

### Getting started with FragPipe

::: {.callout-note}
Some of the information you will need in this section can be found in **Supplementary Information** to the study. Open the **Supplementary Information** and go to page 25, **Supplementary Methods**.

Go to the “Workflow” tab to set up the workflow for the analysis and import the data you have just downloaded.

::: {.question}
Which workflow should you select? HINT: How many TMT tags are listed in the table in Supplementary Data 1?
Which workflow should you select? **Hint**: What labeling method was used in the study?

Click ‘Load workflow’ after you have found and selected the correct workflow to be used.

Click "Load workflow" after you have found and selected the correct workflow to be used.

Next, add your files by clicking on “Add files” and locate them in the designated folder for your raw files that you previously created. Assign each file to a separate *experiment* by clicking "Consecutive".

Go to the "Quant (Isobaric)" tab. Here, you need to provide annotations for TMT channels. Use the five pool annotations that you downloaded from this page.
You will need to upload them to Ucloud and specify the corresponding annotation file for each experiement in order.

Now you should relocate to the “Database” tab. Here you can either download or browse for an already preexisting database file. In this case, we will simply download the latest database file by clicking the "Download" button in FragPipe.

Next, you can go to the "MSFragger" tab to adjust the parameter settings for the search and matching of the theoretical and experimental peptide spectra.
The search parameters to be used are listed in **Supplementary Methods**.

Next, you can go to the MSFragger tab to adjust the parameter settings for the search and matching of the theoretical and experimental peptide spectra.

Most of the settings used for MSFragger can be obtained from the paper *NAME OF PAPER*, which is referred to in the Methods and Materials section.
::: {.question}
What parameters did you set?

When all settings have been obtained, MSFragger should look something like this:

You can also skip configuring MSFragger manually and just use this [parameter file](https://github.com/hds-sandbox/proteomics-sandbox/blob/webpage/fragger.params).
You will need to upload it to UCloud and then load it on the "MSFragger" tab in FragPipe.
:::


Finally, we can navigate to the “Run” tab and run the analysis. For that, we must choose an output directory for the results of the search made by FragPipe. Once you have adjusted that, you are ready to click on “Run”.

This process might take some time, so make sure that you still have enough hours allocated on your job on UCloud—otherwise, it will get terminated. Meanwhile, you can answer these questions:

### Supplementary Data

Before we proceed and download the data available from the paper, we must first delve into some of the details in Supplementary Data 1. This is a large table containing the quantitative proteome data from the Oslo2 breast cancer cohort, which includes 45 subgroups of cancer tumors and relates to Figures 1-6 in the paper.
Before we proceed and download the data available from the paper, we must first delve into some of the details in Supplementary Data.
Your first task is to look through the Supplementary Data and find the annotation relating the tumor types to the isotopic labels used.

How did you find the required information? Describe the steps you took. How much time did it take?

#### Hint
If you have not been able to find the annotations, open Supplementary Data 1, and then go to the tab called "Tumor annotations".

To better understand the supplementary data, we have prepared guiding questions to aid in interpreting the table. You can find the supplementary data in the paper [here](https://www-nature-com.proxy1-bib.sdu.dk/articles/s41467-019-09018-y#Sec15).
