Appendix: Configuration File Settings

This appendix describes the various configuration parameters that may be adjusted in the pipeline’s configuration settings text files. The settings are organized here into several tables grouping them by subject matter, but in the config file they may be listed in any order.

For boolean variables in the following, 0=False and 1=True in the usual fashion.

Some of the following will be of general interest and many users may wish to change their values; others are mostly of interest for development and debugging.
