Using the Dataset Validator

Introduction

To facilitate the loading of new studies into its database, cBioPortal provides a set of staging files formats for the various data types. To validate your files you can use the dataset validator script.

Running the validator

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

./validateData.py --help

This will tell you the parameters you can use:

usage: validateData.py [-h] -s STUDY_DIRECTORY
[-u URL_SERVER | -p PORTAL_INFO_DIR | -n]
[-P PORTAL_PROPERTIES] [-html HTML_TABLE]
[-e ERROR_FILE] [-v] [-r] [-m] [-a MAX_REPORTED_VALUES]
cBioPortal study validator
optional arguments:
-h, --help show this help message and exit
-s STUDY_DIRECTORY, --study_directory STUDY_DIRECTORY
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:8080
-p PORTAL_INFO_DIR, --portal_info_dir PORTAL_INFO_DIR
Path to a directory of cBioPortal info files to be
used instead of contacting a server
-n, --no_portal_checks
Skip tests requiring information from the cBioPortal
installation
-P PORTAL_PROPERTIES, --portal_properties PORTAL_PROPERTIES
portal.properties file path (default: assumed hg19)
-html HTML_TABLE, --html_table HTML_TABLE
path to html report output file
-e ERROR_FILE, --error_file ERROR_FILE
File to which to write line numbers on which errors
were found, for scripts
-v, --verbose report status info messages in addition to errors and
warnings
-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
-a MAX_REPORTED_VALUES, --max_reported_values MAX_REPORTED_VALUES
Cutoff in HTML report for the maximum number of line
numbers and values encountered to report for each
message. 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"

For more information on the --portal_info_dir option, see Offline validation below. If your cBioPortal is not using hg19, you must use the --portal_properties option. For more information, see Validation of non-human data.

When running the validator with parameter -r the validator will run the validation of the clinical data it will ignore all failing checks about values in the headers of the clinical data file.

When running the validator with parameter -m the validator will run the validation of the specific MAF file checks for the mutation file in strict maf check mode. This means that when the validator encounters these validation checks it will report them as an error instead of a warning.

Example 1: test study_es_0

As an example, you can try the validator with one of the test studies found in <cbioportal_source_folder>/core/src/test/scripts/test_data. Example, assuming port 8080 and using -v option to also see the progress:

./validateData.py -s ../../../test/scripts/test_data/study_es_0/ -u http://localhost:8080 -v

Offline validation

The validation script can be used offline, without connecting to a cBioPortal server. The tests that depend on information specific to the portal (which clinical attributes and cancer types have been previously defined, and which Entrez gene identifiers and corresponding symbols are supported), will instead be read from a folder with .json files generated from the portal.

Example 3: validation with a portal info folder

To run the validator with a folder of portal information files, add the -p/--portal_info_dir option to the command line, followed by the path to the folder:

Example 4: generating the portal info folder

The portal information files can be generated on the server, using the dumpPortalInfo script. Go to <cbioportal_source_folder>/core/src/main/scripts, make sure the environment variables $JAVA_HOME and $PORTAL_HOME are set, and run dumpPortalInfo.pl with the name of the directory you want to create:

export JAVA_HOME='/usr/lib/jvm/default-java'
export PORTAL_HOME=<cbioportal_configuration_folder>
./dumpPortalInfo.pl /home/johndoe/my_portal_info_folder/

Example 5: validating without portal-specific information

Alternatively, you can run the validation script with the -n/--no_portal_checks flag to entirely skip checks relating to installation-specific metadata. Be warned that files succeeding this validation may still fail to load (correctly).

./validateData.py -s ../../../test/scripts/test_data/study_es_0/ -n -v

Validation of non-human data

When importing a study, the validator assumes by default that the following parameters from portal.properties are set to:

species=human
ncbi.build=37
ucsc.build=hg19

cBioPortal is gradually introducing support for mouse. If you want to load mouse studies and you have set up your database for mouse, you should set the previous parameters to:

species=mouse
ncbi.build=38
ucsc.build=mm10

If your portal.properties does not have the default (human) settings, you should introduce a new parameter -P in your command. This parameter should point to either portal.properties or a file which contains the new global variables.

As an example, the command for the "Example 1" listed above incorporating the -P parameter is given:

./validateData.py -s ../../../test/scripts/test_data/study_es_0/ -P ../../../../../src/main/resources/portal.properties -u http://localhost:8080 -v

Running the validator for multiple studies

The importer folder <cbioportal_source_folder>/core/src/main/scripts/importer also contains a script for running the validator for multiple studies:

./validateStudies.py --help

The following parameters can be used:

usage: validateStudies.py [-h] [-d ROOT_DIRECTORY] [-l LIST_OF_STUDIES]
[-html HTML_FOLDER]
[-u URL_SERVER | -p PORTAL_INFO_DIR | -n]
[-P PORTAL_PROPERTIES] [-m] [-a MAX_REPORTED_VALUES]
Wrapper where cBioPortal study validator is run for multiple studies
optional arguments:
-h, --help show this help message and exit
-d ROOT_DIRECTORY, --root-directory ROOT_DIRECTORY
Path to directory with all studies that should be
validated
-l LIST_OF_STUDIES, --list-of-studies LIST_OF_STUDIES
List with paths of studies which should be validated
-html HTML_FOLDER, --html-folder HTML_FOLDER
Path to folder for output HTML reports
-u URL_SERVER, --url_server URL_SERVER
URL to cBioPortal server. You can set this if your URL
is not http://localhost:8080
-p PORTAL_INFO_DIR, --portal_info_dir PORTAL_INFO_DIR
Path to a directory of cBioPortal info files to be
used instead of contacting a server
-n, --no_portal_checks
Skip tests requiring information from the cBioPortal
installation
-P PORTAL_PROPERTIES, --portal_properties PORTAL_PROPERTIES
portal.properties file path (default: assumed hg19)
-m, --strict_maf_checks
Option to enable strict mode for validator when
validating mutation data
-a MAX_REPORTED_VALUES, --max_reported_values MAX_REPORTED_VALUES
Cutoff in HTML report for the maximum number of line
numbers and values encountered to report for each
message. 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"

Parameters --url_server, --portal_info_dir, --no_portal_checks and --portal_properties are equal to the parameters with the same name in validateData.py. The script will save a log file with validation output (log-validate-studies.txt) and output the validation status from the input studies:

=== Validating study ../../../test/scripts/test_data/study_es_0
Result: VALID (WITH WARNINGS)
=== Validating study ../../../test/scripts/test_data/study_es_1
Result: INVALID
=== Validating study ../../../test/scripts/test_data/study_es_invalid
directory cannot be found: ../../../test/scripts/test_data/study_es_invalid
Result: INVALID (PROBLEMS OCCURRED)

Example 1: Root directory parameter

Validation can be run for all studies in a certain directory by using the --root-directory parameter. The script will append each folder in the root directory to the study list to validate:

./validateStudies.py -d ../../../test/scripts/test_data/

Example 2: List of studies parameter

Validation can also be run for specific studies by using the --list-of-studies parameter. The paths to the different studies can be defined and seperated by a comma:

./validateStudies.py -l ../../../test/scripts/test_data/study_es_0,../../../test/scripts/test_data/study_es_1

Example 3: Combination root directory and list of studies parameter

Validation can also be run on specific studies in a certain directory by combining the --root-directory and --list-of-studies parameter:

./validateStudies.py -d ../../../test/scripts/test_data/ -l study_es_0,study_es_1

Example 4: HTML folder parameter

When HTML validation reports are desired, an output folder for these HTML files can be specified. This folder does not have to exist, the script can create the folder. The HTML validation reports will get the following name: <study_name>-validation.html. To create HTML validation reports for each study the --html-folder parameter needs to be defined:

./validateStudies.py -d ../../../test/scripts/test_data/ -l study_es_0,study_es_1 -html ../../../test/scripts/test_data/validation-reports
