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.
gemini load -v my.vcf -t snpEff my.db
-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. -t must be text
-o uniq_list. Create a comma-separated list of the distinct (i.e., non-redundant) observed values. -t must be text
-o sum. Compute the sum of the values. They must be numeric.
