garjus 1.3.8

Python package for managing imaging research projects in REDCap and XNAT

garjus

Garjus manages neuroimaging research projects stored in REDCap and XNAT. Integration with DAX allows subject-level processing as well as group-level multi-project analyses. Automations provide data curation, extraction and transformation. All required settings are stored in REDCap. Automation activity is logged in REDCap. Any issues encountered are recorded in REDCap. Progress reports and snapshots are stored in REDCap.

Try dashboard

If you have data in both XNAT and REDCap, garjus will likely be useful. For maximum utility, data will be curated to include consistent session types and scan types. Garjus provides tools to help automate this curation process. Typically, a garjus update will run as a scheduled process. An update usually takes a few minutes unless there are new image sessions to import.

Garjus maintains a stats database of imaging measurements for quick-access and dynamic export.

Other tools include double data entry with compare and image03 to handle uploads to the NDA repository.

All can be utilized in python scripts or via the command-line interface. A current view can be had in the dashboard which provides a single point of access to data in XNAT/REDCap.

At CCMVUMC, garjus is used to automate EEG/MRI/PET image processing as well as manage related data including E-Prime, Gaitrite, NIH Toolbox, NIH Examiner, Fitbit, LifeData, ARC app, etc. Automations are initially triggered when a user enters the scan identifier from the scanner and continue all the way through to analysis.

Quickstart

If you have data in REDCap and XNAT, but have not configured them for garjus follow the steps in setup.

To use an existing garjus system, you will simply need to configure your credentials.

The latest release can be installed from PYPI.

pip install garjus

using garjus in python

from garjus import Garjus

g = Garjus()

The main Garjus class provides data access methods that all return a Pandas DataFrame.

g.activity()
g.analyses()
g.assessors()
g.automations()
g.issues()
g.phantoms()
g.processing_protocols()
g.progress()
g.scans()
g.subjects()
g.subject_assessors()
g.stats(project)
g.tasks()

To get the columns in each dataframe:

g.column_names('issues')
g.column_names('scans')

These Garjus methods returns names in a list:

g.stattypes(project)
g.scantypes(project)
g.proctypes(project)
g.stats_assessors(project)
g.stats_projects()
