title: Is it possible to replace the existing alignment tools such as HISAT and Freebayes with other tools?
box_type: question

contributors: [subinamehta]
---

The tools in this workflow are customizable, however, the user has to ensure that the inputs are in the correct format, while using the same reference genome database.

title: Why do we change the chromosome names in the Ensembl GTF to match the UCSC genome reference?
box_type: question
layout: faq
contributors: [subinamehta]
---

UCSC chromosome names begin with the prefix `chr`, but Ensembl chromosome names do not. For example, chromosome 19 would be denoted as `chr19` in UCSC, and as `19` in Ensemble. Most tools would view those as different when looking for matches/overlaps. Therefore it is always a good idea to make sure these match before you perform any downstream analysis.

If you get stuck or would like to see what the results should look like, you can have a look at one of the following public histories:

title: Can I use these workflows on datasets generated from our laboratory?
area: proteogenomics general
box_type: question

contributors: [subinamehta]
---

Yes, the workflows can be used on other datasets as well. However, you will need to consider data acquisition and sample preparation methods so that the tool parameters can be adjusted accordingly.

title: The workflows contain several Query tabular for text manipulation, is there a tutorial for that?
area: proteogenomics general
box_type: question
layout: faq
contributors: [subinamehta]
---

Query tabular loads a tabular database and creates a sqlite database and tabular file. To learn more about SQL Queries - please look at [this documentation](https://www.sqlite.org/docs.html).

The help section on the Query Tabular tool provides simple examples of both filtering the input tabular datasets, as well as examples of SQL queries. Query Tabular also incorporates regex functions that can be used queries. The PSM report datasets in these tutorials have fields that are lists of protein IDs.

Query Tabular help shows how to normalize those protein list fields so that we can perform operations by protein ID. See section: *Normalizing by Line Filtering into 2 Tables* in the tool help (below the tool in Galaxy).

title: What kind of variants are seen in the output?
area: proteogenomics general
box_type: question
layout: faq
contributors: [subinamehta]
---

From this workflow we can see insertions, deletions, SNVs, or we will know whether it's an intron, exon, splice junction etc.

title: Why do we have a variant mapping file when it is not being used in the workflow?
box_type: question
layout: faq
contributors: [subinamehta]
---

We are working on updating the existing annotation tool to include the variant mapping file. Once that is done, the variant mapping file will also be an input for those tools.

title: In the MVP platform, is it possible to view the genomic location of all the peptides?
box_type: question

Not really, you can only view the genomic localization of the peptides that were present in the genomic mapping file (output from the first workflow).

title: How many search engines can you use in SearchGUI?
box_type: question

SearchGUI has options to use upto 9 search algorithms. However, running all at the same time can be time consuming. According to our initial test, upto 4 search engines can give you good results.
