The returned character set options are intended for situations in which the wlmscpfs application will return attribute values which are not composed of characters from the DICOM default character repertoire. In such cases, for example option --return-iso-ir-100 can be used to specify that a response to a modality's worklist management C-FIND request shall contain DICOM's Specific Character Set attribute (0008,0005) with a corresponding value, indicating the character repertoire from which the characters of returned attribute values were taken (in this example the repertoire ISO IR 100). Please note that the wlmscpfs application will not make sure that all returned values are actually made up of this character repertoire; the application expects this to be the case.
In general, the Specific Character Set attribute (0008,0005) will only be included in the C-FIND response if it contains any attributes that are affected by the character set, i.e. for value representations PN, LO, LT, SH, ST and UT.
Please note that a C-FIND request which is handled by this application may contain DICOM's Specific Character Set attribute (0008,0005), but this application will never use this attribute's value for matching. Besides, the question if DICOM's Specific Character Set attribute (0008,0005) will be contained in a C-FIND response which is returned by this application is always determined by the returned character set option which was specified when this application was started.
The options --enable-file-reject and --disable-file-reject can be used to enable or disable a file rejection mechanism which makes sure only complete worklist files will be used during the matching process. A worklist file is considered to be complete if it contains all necessary type 1 information which the SCP might have to return to an SCU in a C-FIND response message. Table K.6-1 in part 4 annex K of the DICOM standard lists all corresponding type 1 attributes (see column "Return Key Type").
VerificationSOPClass 1.2.840.10008.1.1 FINDModalityWorklistInformationModel 1.2.840.10008.5.1.4.31
The wlmscpfs application will accept presentation contexts for all of the abovementioned supported SOP Classes using any of the transfer syntaxes:
LittleEndianImplicitTransferSyntax 1.2.840.10008.1.2 LittleEndianExplicitTransferSyntax 1.2.840.10008.1.2.1 BigEndianExplicitTransferSyntax 1.2.840.10008.1.2.2
The default behaviour of the wlmscpfs application is to prefer transfer syntaxes having an explicit encoding over the default implicit transfer syntax. If wlmscpfs is running on big-endian hardware it will prefer BigEndianExplicit to LittleEndianExplicit transfer syntax (and vice versa). This behaviour can be changed with the --prefer options (see above).
The wlmscpfs application does not support extended negotiation.
Currently, the wlmscpfs application supports the following attributes as matching keys:
(0008,0050) AccessionNumber (0008,0090) ReferringPhysicianName (0010,0010) PatientName (0010,0020) PatientID (0010,0030) PatientBirthDate (0010,0040) PatientSex (0032,1032) RequestingPhysician (0038,0010) AdmissionID (0040,0100) ScheduledProcedureStepSequence (0008,0060) > Modality (0040,0001) > ScheduledStationAETitle (0040,0002) > ScheduledProcedureStepStartDate (0040,0003) > ScheduledProcedureStepStartTime (0040,0006) > ScheduledPerformingPhysicianName (0040,1001) RequestedProcedureID (0040,1003) RequestedProcedurePriority

The attribute (0008,0005) SpecificCharacterSet is a special case and its support by wlmscpfs is discussed in the NOTES section above.
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 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 behaviour 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 to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file <datadir>/dumppat.txt).
The default behaviour 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.
