NAME

dcmgpdir - Create a general purpose DICOMDIR

SYNOPSIS

dcmgpdir [options] dcmfile-in...

DESCRIPTION

The dcmgpdir utility creates a DICOMDIR file from the specified referenced DICOM files according to the DICOM Part 11 Media Storage Application Profiles.

Currently, the following profiles are supported:

o General Purpose CD-R Interchange (STD-GEN-CD)
o General Purpose Interchange on DVD-RAM Media (STD-GEN-DVD-RAM)
dcmmkdir is an extended version of this tool which also supports other Media Storage Application Profiles than the general purpose one (e.g. both cardio profiles requiring the use of icon images).

PARAMETERS

dcmfile-in referenced DICOM file

-m --keep-filenames: expect filenames to be in DICOM format (default)
+m --map-filenames: map to DICOM filenames (lowercase->uppercase,
and remove trailing period)
-r --no-recurse: do not recurse within directories (default)
+r --recurse: recurse within filesystem directories
+p --pattern [p]attern : string (only with --recurse): pattern for filename matching (wildcards); # possibly not available on all systems
checking:: -W --no-consistency-check

+W --warn-inconsist-files: warn about inconsistent files (default)
-a --abort-inconsist-file: abort on first inconsistent file
+Ipi --invent-patient-id: invent new PatientID in case of inconsistent
PatientsName attributes
output options: writing:

-A --replace
replace existing DICOMDIR (default)

+A --append

append to existing DICOMDIR
-w --discard: do not write out DICOMDIR
-nb --no-backup: do not create a backup of existing DICOMDIR
post-1993 value representations:: +u --enable-new-vr
enable support for new VRs (UN/UT) (default)
-u --disable-new-vr: disable support for new VRs, convert to OB
group length encoding:: -g --group-length-remove
write without group length elements (default)
+g --group-length-create: write with group length elements
length encoding in sequences and items:: +e --length-explicit
write with explicit lengths (default)
-e --length-undefined: write with undefined lengths

NOTES

All files specified on the command line (or discovered by recursivly examining the contents of directories with the +r option) are first evaluated for their compatibility with the General Purpose CD-R Image Interchange Profile (Supplement 19). Only appropriate files encoded using the Explicit VR Little Endian Uncompressed Transfer Syntax will be accepted. Files having invalid filenames will be rejected (the rules can be relaxed via the +m option). Files missing required attributes will be rejected (the +I option can relax this behaviour).
A DICOMDIR file will only be constructed if all files have passed initial tests.

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) 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 share/data/dumppat.txt).

ENVIRONMENT

The dcmgpdir 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 <PREFIX>/lib/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. 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.
