Using the metaImport Script

Importing Data into cBioPortal

The metaImport script should be used to automate the process of validating and loading datasets. It also has some nice features like an extra option to only load datasets that completely pass validation (i.e. with no errors, while warnings can be explicitly allowed by the user).

Running the metaImport Script

To run the metaImport script first go to the importer folder <your_cbioportal_dir>/core/src/main/scripts/importer and then run the following command:

./ -h

This will tell you the parameters you can use:

$./ -h
usage: [-h] -s STUDY_DIRECTORY
[-jar JAR_PATH] [-html HTML_TABLE]
[-v] [-o] [-r] [-m] [-a MAX_REPORTED_VALUES]
cBioPortal meta Importer
optional arguments:
-h, --help show this help message and exit
path to directory.
-u URL_SERVER, --url_server URL_SERVER
URL to cBioPortal server. You can set this if your URL
is not http://localhost/cbioportal
-p PORTAL_INFO_DIR, --portal_info_dir PORTAL_INFO_DIR
Path to a directory of cBioPortal info files to be
used instead of contacting the web API
-n, --no_portal_checks
Skip tests requiring information from the cBioPortal
-jar JAR_PATH, --jar_path JAR_PATH
Path to scripts JAR file (default: locate it relative
to the import script)
-html HTML_TABLE, --html_table HTML_TABLE
path to html report
-v, --verbose report status info messages while validating
-o, --override_warning
override warnings and continue importing
-r, --relaxed_clinical_definitions
Option to enable relaxed mode for validator when
validating clinical data without header definitions
-m, --strict_maf_checks
Option to enable strict mode for validator when
validating mutation data
Cutoff in report for the maximum number of line
numbers and values encountered to report for each
message in the HTML report. For example, set this to a
high number to report all genes that could not be
loaded, instead of reporting "(GeneA, GeneB, GeneC,
213 more)".

Example of Importing a study

Export PORTAL_HOME as explained here, e.g.

export PORTAL_HOME=<cbioportal_configuration_folder>

and then run (this simple command only works if your cBioPortal is running at http://localhost/cbioportal - if this is not the case, follow the advanced example):

./ -s ../../../test/scripts/test_data/study_es_0/

Advanced Example

This example imports the study to the localhost, creates an html report and shows status messages.

./ -s ../../../test/scripts/test_data/study_es_0/ -u http://localhost:8080 -html myReport.html -v

By adding -o, warnings will be overridden and import will start after validation.

Development / debugging mode

For developers and specific testing purposes, an extra script,, is available which imports data regardless of validation results. Check this page for more information on how to use it.
