Appendix A Config File

Data Transfer Tool Configuration File

The DTT has the ability to save and reuse configuration parameters in the format of a flat text file via a command line argument. A simple text file needs to be created first with an extension of either txt or dtt. The supported section headers are upload and download which can be used independently of each other or used in the same configuration file. Each section header corresponds to the main functions of the application which are to either download data from the GDC portals or to upload data to the submission system of the GDC. The configurable parameters are those listed in the help menus under either download or upload.

Example usage:

gdc-client download d45ec02b-13c3-4afa-822d-443ccd3795ca --config my-dtt-config.dtt

Example of configuration file:

[upload]
path = /some/upload/path
upload_part_size = 1073741824


[download]
dir = /some/download/path
http_chunk_size = 2048
retry_amount = 6
