Supported search terms for finding samples
Our search is 'contains' search, meaning the term you enter can be at the beginning, end or in the middle of a matched term. Our search is case-independent. An example is
will match 'Stage IIIA' and 'Stage IIA'. To specify a specific string, use quotes
You can specify a certain column and mathematical expression such as
which will find all values greater than 2 in the first column. We support the following operators
- = (equal)
- >= (less than or equal)
- >= (greater than or equal)
- < (less than)
- > (greater than)
- != (not equal)
You can search any annotation on a mutation, such as the functional impact, protein position, or gene name itself
To find all samples with mutations with the protein change, enter:
To find all samples where the functional impact has the text 'frame' or 'nonsense' in it:
frame OR nonsense
To find all samples that have a mutation, search the gene annotation:
To find all samples that do not have a mutation, use the negation of the gene annotation:
To find all samples that do not have data in one or more columns, use:
and choose 'Remove samples'. To find all samples that do not have data for just one column, use:
Enter a sample ID to find a sample of interest. An example:
If you are searching for multiple sample IDs, you will need to separate each by an 'OR'. You can copy and paste a list of sample IDs into the search bar as long as they are separated by a space, tab, or return (new line).
TCGA-DB-A4XH OR TCGA-2F-A9KO-01 OR TCGA-02-0001
To make it easy to search a specific column, we use shorthand to annotate the first column as 'A:', the second as 'B:', etc. An example is
This will search ONLY the first column for the word 'YES'. Note that we will retain your original search if you move the columns around.
You can enter multiple search terms and we will match all of them with an implicit 'AND'. We also support 'OR'.
Use parentheses to group search terms. For example:
"Stage II" (B:Negative OR C:Negative)
will search for samples that match 'Stage II' in any column and are 'Negative' for either the second or third column.
You can also use '!=' to negate a term such as:
which will match all samples that have data across all columns.
