• cdex <source csv file>
• cdex <source csv file> <changed csv file>
• cdex --target <target covariate name > <source csv file>
• cdex --target <target covariate name > <source csv file> <changed csv file>

When the program starts, it lists all of the tagged covariates in the source CSV file. It also performs several validity checks on the CSV file, and warns of any issues it finds that would cause analysis to fail.

When the changed csv file name is not specified on the command line, the source will be proposed as the default. You can edit it using left and right arrows, HOME, END, backspace, and text insertion, then press RETURN when it is complete. ESC will exit without saving.

After any editing, if the specified save as path and file name would overwrite the source, you are warned and asked if it is OK to proceed.

when the --target covariate name is specified, you are asked to verify the change, and it will be made immediately.

When the --target command line option is not specified, you may change as many covariate tags as you wish, and specify any valid flag to apply to each selected covariate.
