Step 1: Change Working Directory 

During the CRC Data Installation we will be working with the crcdata directory. Within this directory are the files you will be editing to define the database properties, create the crcdata tables and load the sample data provided with the i2b2 on OMOP data package.

Working directory for crcdata: YOUR_I2B2_OMOP_DATA_DIR\i2b2_omop_data\{oracle|sqlserver}\CRCdata

How to Change Directories

If you are not familiar with how to change your directory in either a windows command prompt or a terminal window, you can enter the following:

Change Directory Command

cd YOUR_I2B2_OMOP_DATA_DIR\i2b2_omop_data\{oracle|sqlserver}\CRCdata


Make sure you replace the following when entering the above command:

  • YOUR_I2B2_OMOP_DATA_DIR is the location where you unzipped the i2b2 omop data package.
  • oracle|sqlserver is the type of database management system used for your CDM database.

info Important

The change directory command shown above is written for Windows. The command itself is the same for both Linux and Windows with the only exceptions being the slashes in the path name and Linux does not include the "drive".
  • Linux Path: use a forward slash.
  • Windows Path: use a backward slash.


Linux Command: CD /opt/data/i2b2_omop_data/oracle/CRCdata

Windows Command: CD C:\opt\data\i2b2_omop_data\oracle\CRCdata
