GEMINI provides a sub-command called annotate for exactly this purpose. - -**Details** - -It is inevitable that researchers will want to enhance the GEMINI framework with their own, custom annotations. GEMINI provides a sub-command called annotate for exactly this purpose. As long as you provide a tabix‘ed annotation file in BED or VCF format, the annotate tool will, for each variant in the variants table, screen for overlaps in your annotation file and update a one or more new column in the variants table that you may specify on the command line. This is best illustrated by a following **example**. - -**Input files** - -Let’s assume you have already created a GEMINI database of a **VCF file** using the *load module*. - -Now, let’s imagine you have an annotated file in **BED format** (important.bed) that describes regions of the genome that are particularly relevant to your lab’s research. You would like to annotate in the GEMINI database which variants overlap these crucial regions. We want to store this knowledge in a new column in the variants table called important_variant that tracks whether a given variant overlapped (1) or did not overlap (0) intervals in your annotation file. - - *To do this, you must first TABIX your BED file* - -**-a boolean - Did a variant overlap a region or not?** - -Now, you can use this *TABIX*’ed file to annotate which variants overlap your important regions. In the example below, the results will be stored in a new column called “important”. The **-t boolean** option says that you just want to track whether (1) or not (0) the variant overlapped one or more of your regions. - -Since a new columns has been created in the database, we can now directly query the new column. In the example results below, the first and third variants overlapped a crucial region while the second did not:: - - chr22 100 101 1 1 - chr22 200 201 2 0 - chr22 300 500 3 1 - -**-a count - How many regions did a variant overlap?** - -Instead of a simple yes or no, we can use the **-t count** option to count how many important regions a variant overlapped. It turns out that the 3rd variant actually overlapped two important regions:: - - chr22 100 101 1 1 - chr22 200 201 2 0 - chr22 300 500 3 2 - -**-a extract - Extract specific values from a BED file** - -Lastly, we may also extract values from specific fields in a BED file (or from the INFO field in a VCF) and populate one or more new columns in the database based on overlaps with the annotation file and the values of the fields therein. To do this, we use the **-a extract** option. - -This is best described with an example. To set this up, let’s imagine that we have a VCF file from a different experiment and we want to annotate the variants in our GEMINI database with the allele frequency and depth tags from the INFO fields for the same variants in this other VCF file. - -Now that we have a proper *TABIX*’ed VCF file, we can use the **-a extract** option to populate new columns in the GEMINI database. In order to do so, we must specify: - - 1) its type (e.g., text, int, float,) (**-t**) - 2) the field in the INFO column of the VCF file that we should use to extract data with which to populate the new column (**-e**) - 3) what operation should be used to summarize the data in the event of multiple overlaps in the annotation file (**-o**) - 4) (optionally) the name of the column we want to add (**-c**), if this is not specified, it will use the value from **-e**. - -For example, let’s imagine we want to create a new column called “other_allele_freq” (**-c**) using the AF field in our VCF file to populate it. - -This create a new column in my.db called other_allele_freq and this new column will be a FLOAT (**-t float**). In the event of multiple records in the VCF file overlapping a variant in the database, the average (**-o mean**) of the allele frequencies values from the VCF file will be used. - -At this point, one can query the database based on the values of the new other_allele_freq column (using **GEMINI query**). - -**-t TYPE - Specifying the column type(s) when using -a extract** - -The annotate tool will create three different types of columns via the **-t** option: - - 1) Floating point columns for annotations with decimal precision as above (-t float) - 2) Integer columns for integral annotations (-t integer) - 3) Text columns for string columns such as “valid”, “yes”, etc. (-t text) - - *The -t option is only valid when using the -a extract option.* - -**-o OPERATION - Specifying the summary operations when using -a extract** - -In the event of multiple overlaps between a variant and records in the annotation file, the annotate tool can summarize the values observed with multiple options: - - - -o mean Compute the average of the values. They must be numeric. - - -o median Compute the median of the values. They must be numeric. - - -o min Compute the minimum of the values. They must be numeric. - - -o max Compute the maximum of the values. They must be numeric. - - -o mode Compute the maximum of the values. They must be numeric. - - -o first Use the value from the first record in the annotation file. - - -o last Use the value from the last record in the annotation file. - - -o list Create a comma-separated list of the observed values. - - -o uniq_list Create a comma-separated list of the distinct observed values. - - -o sum Compute the sum of the values. They must be numeric. - -The -o option is only valid when using the -a extract option. - -**Annotating with VCF** - -Most of the examples to this point have pulled a column from a tabix indexed bed file. It is likewise possible to pull from the INFO field of a tabix index VCF. The syntax is identical but the **-e** operation will specify the names of fields in the INFO column to pull. By default, those names will be used, but that can still be specified with the **-c column**. - -To put a DP column in the db, set: - - -o list, -e DP, -t integer - -... and name it 'depth', set: - - -o list, -e DP, -c depth, -t integer - - -Missing values are allowed since we expect that in some cases an annotation VCF will not have all INFO fields specified for all variants. - -*We recommend decomposing and normalizing variants before annotating. See Step 1. split, left-align, and trim variants for a detailed explanation of how to do this. To do that see the GEMINI* preprocessing_ *website.* - -**Extracting and populating multiple columns at once** - -One can also extract and populate multiple columns at once by providing comma-separated lists (no spaces) of column names (**-c**), types (**-t**), numbers (**-e**), and summary operations (**-o**). For example, recall that in the VCF example above, we created a *TABIX*’ed BED file containg the allele frequency and depth values from the INFO field as the 4th and 5th columns in the BED, respectively. - -Instead of running the annotate tool twice (once for each column), we can run the tool once and load both columns in the same run. For example with settings: - - - -a extract - - -c other_allele_freq,other_depth - - -t float,integer - - -e 4,5 - - -o mean,max - -We can then use each of the new columns to filter variants with a *GEMINI query*: - -.. _preprocessing: https://gemini.readthedocs.org/en/latest/content/preprocessing.html#preprocess - +Given an existing GEMINI database and an annotation source in BED or VCF +format, the annotate tool will, for each variant in the variants table of the +database, screen for overlapping regions defined in the annotation source and +update one or more new columns of the variant record in the database based on +the result and the annotation found. ]]></help> <expand macro="citations"/> </tool>
