storescp(1) OFFIS DCMTK storescp(1)NAMEstorescp - DICOM storage (C-STORE) SCP
SYNOPSISstorescp [options] [port]
DESCRIPTION
The storescp application implements a Service Class Provider (SCP) for
the Storage Service Class. It listens on a specific TCP/IP port for
incoming association requests from a Storage Service Class User (SCU)
and can receive both DICOM images and other DICOM composite objects.
The storescp application also supports the Verification Service Class
as an SCP.

NOTES
The semantic impacts of the above mentioned options is clear for the
majority of options. Some particular options, however, are so specific
that they need detailed descriptions which will be given in this
passage.
Option --sort-conc-studies enables a user to sort all received DICOM
objects into different subdirectories. The sorting will be done with
regard to the studies the individual objects belong to, i.e. objects
that belong to the same study will be stored in the same subdirectory.
In general, a DICOM object d_n+1 is considered to belong to the same
study as a DICOM object d_n if and only if d_n and d_n+1 show the exact
same values in attribute Study Instance UID. The names of the resulting
subdirectories always start with a prefix p which was passed to this
option as a parameter. In addition to this prefix, the subdirectory
names contain time stamp information with regard to the date and time
of reception of this particular study's first DICOM object. In detail,
the determination of the subdirectory names pertains to the pattern
[prefix]_[YYYYMMDD]_[HHMMSSPPP]
where YYYY refers to year (4 digits), MM to month (01-12), DD to day
(01-31), HH to hour (00-23), MM to minute (00-59), SS to second (00-59)
and PPP to milliseconds (000-999). If the prefix is an empty string,
the first '_' is omitted.
The other --sort-xxx options work in a similar manner, only the
subdirectory names are created differently. For option --sort-on-study-
uid the pattern is
[prefix]_[StudyInstanceUID]
and for option --sort-on-patientname
[PatientName]_[YYYYMMDD]_[HHMMSSPPP]
where 'PatientName' is replaced by 'ANONYMOUS' if the data element is
empty or absent in the data set. Please note, however, that for option
--sort-on-study-uid the same subdirectory will be used for all DICOM
objects that belong to the same study, i.e. in contrast to the other
--sort-xxx options there is no guarantee that a study directory is ever
completed.
Option --timenames creates filenames from timestamps corresponding to
the time, storescp writes a file to disk. The format is
[YYYYMMDDHHMMSSPPP]_[SERIALNO].[MD]
where YYYY, MM, DD, HH, MM, SS, PPP are interpreted as described above.
If more files are created at the same time, SERIALNO is inserted. It
consists of a 4-digit, consecutive number (0000 to 9999). For the first
file, that exists for a specific time, no number (and no '_') is
inserted at all. MD represents an identification code (2 letters) for
the kind of object stored in the file (see notes on --rename-on-
eostudy).
Option --filename-extension appends a specified suffix to each filename
(a dot '.' is not added automatically). This suffix is not appended to
the filenames created by --rename-on-eostudy to maintain the length of
8 characters.
Option --exec-on-reception allows to execute a certain command line
after having received and processed one DICOM object (through a C-
STORE-RQ message). The command line to be executed is passed to this
option as a parameter. The specified command line may contain a number
of placeholders which will be replaced at run time:
· #p: complete path to the output directory into which the last DICOM
object was stored (not available with option --ignore though)
· #f: filename of the current output file (not available with option
--ignore though)
· #a: calling application entity title of the peer Storage SCU
· #c: called application entity title used by the peer Storage SCU to
address storescp
· #r: calling presentation address, i.e. hostname or IP address of the
peer Storage SCU
The specified command line is executed as a separate process, so that
the execution of storescp will not be held back.
Option --exec-on-eostudy allows to execute a certain command line when
all DICOM objects that belong to one study have been received by
storescp. The same placeholders as with --exec-on-reception may be
used, except for '#f', which is not supported. A study is considered
complete by storescp when an object belonging to a different study is
received or the timeout specified with --eostudy-timeout takes place.
If option --rename-on-eostudy is in force, the renaming takes place
before the external command is executed.
Option --rename-on-eostudy refers to the above mentioned --sort-xxx
options and can only be used in combination with one of these options.
If a user specifies option --rename-on-eostudy and storescp determines
that all DICOM objects that belong to a certain study have been
received, all DICOM files that belong to the last study will be renamed
in the corresponding output directory. The filenames into which the
files are being renamed will be calculated using the pattern
[prefix][consecutive numbering]
where [prefix] is a 2 character prefix that reveals the kind of DICOM
object stored in the file and [consecutive numbering] is a
consecutively numbered, 6-digit number, starting at '000001'. In
general, the question if all DICOM objects that belong to one study
have been received by storescp will be answered positively if and only
if two consecutively received DICOM objects d_n and d_n+1 do not show
the same values in attribute Study Instance UID; in such a case, d_n+1
is considered to belong to a new study.
Using option --eostudy-timeout a user can modify the determination
process to figure out if all DICOM objects that belong to one study
have already been received by storescp. With regard to this fact, it is
clear that this option can only be used in combination with at least
one of the following options: --sort-xxx, --exec-on-eostudy and
--rename-on-eostudy. If option --eostudy-timeout is specified, the end
of a study is considered to have occurred not only if two consecutively
received DICOM objects d_n and d_n+1 do not show the same values in
attribute Study Instance UID, but also if whithin a time span of x
seconds after the reception of a DICOM object d_n, no other DICOM
object was received over the network. Note that the amount x of seconds
(which determines the length of this time span) has to be passed to
this option as a parameter.

The storescp application will accept presentation contexts for all of
the abovementioned supported SOP Classes using any of the following
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 storescp application is to prefer transfer
syntaxes having an explicit encoding over the default implicit transfer
syntax. If storescp 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). Using option --accept-all any of the following transfer
syntaxes is supported:
LittleEndianImplicitTransferSyntax 1.2.840.10008.1.2
LittleEndianExplicitTransferSyntax 1.2.840.10008.1.2.1

Additional Storage SOP Classes and Transfer Syntaxes can be used with
the so-called 'association negotiation profiles' (see below).
The storescp application does not support extended negotiation by
default. However, using an appropriate association negotiation profile
(see below) the optional support for extended negotiation can be added
to particular SOP classes.
Access Control
When compiled on Unix platforms with TCP wrapper support, host-based
access control can be enabled with the --access-control command line
option. In this case the access control rules defined in the system's
host access control tables for storescp are enforced. The default
locations of the host access control tables are /etc/hosts.allow and
/etc/hosts.deny. Further details are described in hosts_access(5).
Running storescp from inetd
On Posix platforms, storescp can be initiated through the inetd(8)
super server. This requires that storescp be configured in the
/etc/inetd.conf configuration file. A typical configuration line could
look like this:
acr-nema stream tcp nowait root /usr/sbin/storescp -id +ac -od /tmp/storescp
where -id (--inetd) activates the inetd mode in which the DICOM
association is actually accepted by inetd and passed to storescp, +ac
(--access-control) activates the TCP wrapper based access control
described above and -od (--output-directory) defines the directory in
which storescp stores incoming DICOM objects. Note that the service
name ('acr-nema' in this example) determines the port number on which
DICOM associations are accepted and must be defined in /etc/services.
When runnning from inetd, the stdout and stderr streams are redirected
to files in the /tmp filesystem which can be identified by the filename
starting with the prefix 'storescp_'.
Please note that when run through inetd, storescp is executed with root
privileges, which may be a security risk.
Association Negotiation Profiles and Configuration Files
storescp supports a flexible mechanism for specifying the DICOM network
association negotiation behaviour, based on so-called 'association
negotiation profiles' which may be read from a configuration file. The
format and semantics of this configuration file are documented in
asconfig.txt.
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 storescp 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.
