  • CONQUEST boot automatically start on Ubuntu

    Hi,


    Have a look in linuxmanual.pdf for an example startup script but note that you will need to install the package authbind.
    start/stop scripts need to be copied to /etc/init.d and once you are sure it works can be set to automatically start with

    Code
    sudo upadte-rc.d conquest-pacs.sh defaults

    (assuming conquest-pacs.sh is the name of the script). This will create the proper links in the various rcx.d directories.

  • Dicom server 1.4.16(k) released !

    Hi Marcel,


    When compiling 1416j on my linux system I had an error of too few arguments for mkdir at line 2259 in MyBridgeStorage. I tried copying the define statement at line 2686 above the class and this fixed the error.

  • Lua forward kills system with NULL database

    Hi,


    Gdb appears to show empty storage. Let me know if you want more information.

  • Lua forward kills system with NULL database

    Hello everyone,


    I use lua on a system running linux to modify images before they are sent to another server. This works OK when there is local database but causes a segmentation fault when the database uses the NULL driver. The relevent section from dicom.ini is

    Code
    [lua]ImportConverter0      =  script('forward to TRAEKIPG;');


    The log looks like this:

    Code

    Using strace adds a little more information:

    Code
    ImportConverter-1.0: forwarded object to TRAEKIPG

     <unfinished ...>

    +++ killed by SIGSEGV +++

    Segmentation fault


    If I use the standard importconverter described in DICOM Routing without database everything works OK. I suspect lua does not know where to read the file from when there is no database.

  • Processing files from incoming

    Hi,
    On my linux system, when images are read from the incoming directory they are not processed by import/export or lua. The image is stored correctly and the log file shows that the file has bee added. This means I cannot manipulate images by placing files in the incoming directory.
    Is this the expected behaviour?

  • release candidate 4 of the server version 1.4.16 + rc6-patch

    Hi,


    I found a bug that seems to have been introduced between beta and rc2. findscu from the dicom toolkit (dcmtk) will cause dgate to crash in both windows and linux with rc2 and newer but not beta or older. Logging from the 2 versions look like this.

  • release candidate 4 of the server version 1.4.16 + rc6-patch

    Hi,


    I get a segfault on my Ubuntu linux box when I try to add jpeg encoded files created by gdcmimg (http://sourceforge.net/apps/mediawiki/gdcm).


  • LUA binding - documentation

    This simple script changes the StudyUID of an image when it has previously been refused. The image is sent to Aetitle PAXFIX so that it doesn't get triggered by a normal cmove.
    The error looks like this:

  • Saving rejected images

    Hi,


    Every week I have 1-2 images that the database refuses to enter. The files are dropped and an error is logged. At the moment I search the PacsTrouble log for these errors so that I can manually fix the files and resend them. As a temporary measure I have created a PacsReject log file to separate the errors from the hundreds of warning messages in PacsTrouble. My PacsReject log has entries like this:

    My question is, would it be possible to have a rejected images directory to save these files. If the files were all in one place it would save a lot of time when fixing them.

  • Jasper compile error

    Hello,
    I had the following errors while compiling jasper and worked out how to fix it.

    Code
    jpg_dec.c: In function 'jpg_put_pixel_rows':

    jpg_dec.c:312: error: 'JSAMPLE16' undeclared (first use in this function)

    jpg_dec.c:312: error: (Each undeclared identifier is reported only once

    jpg_dec.c:312: error: for each function it appears in.)

    jpg_dec.c:312: error: 'bufptr16' undeclared (first use in this function)

    jpg_dec.c:329: error: 'JSAMPROW16' undeclared (first use in this function)


    I had already done in jpeg-6c:
    sudo make install
    but also had to add
    sudo make install-lib


    I don't know why the first install did not also install the libraries.

  • Segmentation fault after regendir

    I have found that --deleteseries causes a segfault with mysql but not dbase that might be a related problem. I am not explicitly running gdb but the output is quite informative.



    I also tried it on a series containing only 1 image with similar results.

  • DHCP Clients

    There are a number of factors which will the ease of use of this approach. Basically, if the ip address changes then acrnema.map must be edited.
    If you have control of the dhcp server you can assign the ip based on the MAC address. This is the same principle as fixed ip but more flexible for the client.
    If the pool of available addresses is larger than the number of clients they should get the same address they had from the first connection.
    If the pool is smaller than the number of clients then there is a greater chance of getting a new ip. This is affected by how often the client is disconnected from the network.

  • Linux hardware - NAS combination

    If you want to be a bit more adventurous, most of the NAS devices use variations on the ARM chips and run conquest/mysql quite well.


    I have just replaced a NSLU2 http://en.wikipedia.org/wiki/NSLU2 with an external usb HDD that ran for about 2 years with a DNS323 http://wiki.dns323.info/ with 2 internal SATA drives. Both systems can use the debian-arm distribution which means you can install the gcc compiler, mysql, postgresql, apache etc although it is more of a challenge for the DNS323 which requires a special cable for serial port access.


    Compiling dgate on the NSLU2 took more than 30 minutes compared to under 1 minute for my desktop so I first thought performance might be unacceptably slow but I was surprised that the transfer speeds were quite reasonable. The DNS323 has twice the memory (64MB) and runs even better.


    I can post more details if anyone is interested.
