DCMTK Version 3.7.0 OFFIS DICOM Toolkit

dcmpssnd: Network send for presentation state viewer

# SYNOPSIS

    dcmpssnd [options] config-file target study [series] [instance]

# DESCRIPTION

The dcmpssnd application is invoked by the Grayscale Softcopy Presentation State Viewer and is not intended to be invoked manually. The application reads the common configuration file which is shared between the different components of the viewer, attempts to establish a DICOM association with the selected target and, if successful, selects the required DICOM instances from the viewer's database and transmits them using the DICOM storage service class, which is supported as SCU. When transmission is finished (successfully or unsuccessfully), the application terminates. This application supports the same storage SOP classes as the storescu utility, but does not support encapsulated transfer syntaxes. See the full conformance statement for further details.

# PARAMETERS

    config-file  configuration file to be read

    target       symbolic identifier of send target in config file

    study        study instance UID of study in database to be sent

    series       series instance UID (default: send complete study)

    instance     SOP instance UID (default: send complete series)

             print version information and exit

           --arguments
             print expanded command line arguments

      -q   --quiet
             quiet mode, print no warnings and errors

             verbose mode, print processing details

      -d   --debug
             debug mode, print debug information

      -ll  --log-level  [l]evel: string constant
             (fatal, error, warn, info, debug, trace)
             use level l for the logger

      -lc  --log-config  [f]ilename: string
             use config file f for the logger

# LOGGING

The level of logging output of the various command line tools and underlying libraries can be specified by the user. By default, only errors and warnings are written to the standard error stream. Using option –verbose also informational messages like processing details are reported. Option –debug can be used to get more details on the internal activity, e.g. for debugging purposes. Other logging levels can be selected using option –log-level. In –quiet mode only fatal errors are reported. In such very severe error events, the application will usually terminate. For more details on the different logging levels, see documentation of module "oflog".

In case the logging output should be written to file (optionally with logfile rotation), to syslog (Unix) or the event log (Windows) option –log-config can be used. This configuration file also allows for directing only certain messages to a particular output stream and for filtering certain messages based on the module or application where they are generated. An example configuration file is provided in <etcdir>/logger.cfg.

# COMMAND LINE

All command line tools use the following notation for parameters: square brackets enclose optional values (0-1), three trailing dots indicate that multiple values are allowed (1-n), a combination of both means 0 to n values.

Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behavior conforms to the standard evaluation rules of common Unix shells.

In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator unless they appear between two quotation marks) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows one to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file <datadir>/dumppat.txt).

# ENVIRONMENT

The dcmpssnd utility will attempt to load DICOM data dictionaries specified in the DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable is not set, the file <datadir>/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).

The default behavior should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (":") separates entries. On Windows systems, a semicolon (";") is used as a separator. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
