setred rctred_parfile
Setred is a Perl script which creates or edits the parameters file which is used as input to rctred (for reducing a list of images). Using this script to create the parameters file may help to identify and avoid certain problems when using rctred.
If setred is invoked without any argument, it can be used to create a new parameters file. Default parameter values will be used until changed by the user. The script lists the current parameter values and allows the user to edit them or write them out to a file. A few simple checks on the parameter values' validity can also be made; warnings are issued for parameters which might cause a problem when running rctred. Rctred can also be invoked directly from setred using the current parameters (without writing them to disk). Finally, if the user inputs relative pathnames to files or directories for parameters requiring full pathnames, the user can choose to expand the relative pathnames to full pathnames (if the file or directory exists).
If setred is invoked with a command line argument, it is assumed to be a pre-existing parameters file. Setred may be used to edit this parameters file or use it as a template to create other parameter files.
