NAME

       dcmpschk - Checking tool for presentation states

SYNOPSIS

       dcmpschk [options] [dcmfile-in...]

DESCRIPTION

       The  dcmpschk  utility  checks  DICOM  Grayscale  Softcopy  Presentation State objects for
       conformance with the standard. The test is performed in three phases:

       • Phase 1 checks the Meta-header of the DICOM file. It  is  tested  whether  all  required
         attributes  are  present,  whether the SOP class and instance UIDs match the UIDs in the
         main object and whether the  group  length  attribute  contains  a  correct  value.  The
         Transfer Syntax of the Meta header is also checked.
       • Phase  2  performs  a  syntactic  check  of  the values, value representations and value
         multiplicities for each attribute in the object. The values present in the object  under
         test are compared with the definitions of the DICOM data dictionary.
       • Phase 3 performs a semantic check of the integrity of the Presentation State. This phase
         is omitted when objects of other SOP Classes are encountered. Phase 1 and 2 can also  be
         applied  to other DICOM objects of arbitrary SOP class. It should be noted that dcmpschk
         does not support Presentation States which  contain  the  Mask  Module.  These  will  be
         rejected with a message that the Mask Module is not supported.

                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 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).

ENVIRONMENT

       The  dcmpschk  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 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.
