I am seeing displaced lines in the images. It kind of looks like in some spots that the pixels have been shifted. I'm using Centos 7.6.1810.

I'm seeing an issue tranmitting DX images , whereby a DX has corrupted data after being transmitted from 1.5.0 . Not a lot of corruption , but definite and absolutely traceable to 1.5.0 . I've reverted back to 1.14.19b and the issue is not present there. I can provide more information and potentially a debuglog if you would like to track this down. It seems very specific in 1.5.0 to only affect DX transmissions. I had seen this type of corruption after transmission in 1.14.19c , d, d2 but it was more prevalent in those versions affecting more modalities. Please let me know what I can do to assist tracking this down.

Running Cent 7.6 and I've managed to compile dgate by changing some of the lines in the maklinux script regarding mysql/mariadb. Locations of headers and .so mostly . But now that I've compiled and run I'm getting a couple of errors that are confusing.

First is that the server is telling me that I don't have enough rights to MAG0 when I I'm using the same user to start dgate as created that directory and also I have rwx set for ugo on that directory as well.

error is :

Wed May 13 17:03:39 2020 *** Not enough rights to write in MAG0

directory config:

drwxrwxrwx. 2 root root 21 May 13 16:55 data

MAG0=/usr/local/dicomgate/data

I started dgate as follows:

./dgate -v

Second is the following error ... which i assume is telling me that somehow dgate hasn't been able to connect to the mysql / maridb driver?

Database type: NULL driver (black hole)

Any hints or suggestions would be appreciated .

Thanks in advance

Ok. good to know. I'll either move it to an export converter and test or resolve it in another way. Thanks again.

I'm running I'm on 1.4.19b . I'm wondering if this is the same as bug 64 for version 1.5 alpha .

I've added a simple ImportConverter as follows:

ifequal "%u","CALLINGAE";system php /var/scripts/ConversionJob.php %f %VStudyInstanceUID

This import converter does work but not completely properly. The value sent to my script by %f is different than the actual filename written to the filesystem. It seems to differ by a single incremental value . As an example here are 2 image files that I received to my dgate instance recently and the %f value sent to my script, followed by the actual filename written to the filesystem.

IMAGE #1--------------

%f received by script = /usr/local/dicomgate/data/722006-1752-2019/1.3.46.670589.28.26690171469773220191010230221192396.11112_0000_000001_1571001576002e.dcm

Actual filename written = /usr/local/dicomgate/data/722006-1752-2019/1.3.46.670589.28.26690171469773220191010230221192396.11112_0000_000001_1571001576002f.dcm

IMAGE #2-------------

%f received by script =/usr/local/dicomgate/data/722006-1752-2019/1.3.46.670589.28.26690171469773220191010230154995010.2.2_0002_000002_1571001574002b.dcm

Actual filename written = /usr/local/dicomgate/data/722006-1752-2019/1.3.46.670589.28.26690171469773220191010230154995010.2.2_0002_000002_1571001574002c.dcm

As you can see it looks like the last value is incremented by 1 on each filename. Is this is a known issue in 1.4.19b I can provide more examples if needed as the behavior is very consistent.

In WindowsManual.pdf I found:

[after NN] collect delay in seconds from last image

Cool. Thanks. It all works well

Mr John Bravo

Marcel

Thanks for you quick response. By "after NN" what does NN refer to in this context .

Due to an issue I'm having forwarding a study to a remote (not dgate) pacs upon receipt I need to manually start/spawn local filesystem script or possibly a lua script to work around the issue. This has to be done however after the entire study has been received. Can you tell me how to launch such a process from ExportConverter? or is there a better solution than export converter? Thanks in advance.

Is there a way to grab the current UPACS THREAD number from within the RetrieveOn function? I'd like to add that number to the OperatorConsole output when the server reports that it is "Sending File" . So it would read something like "UPACS THREAD ## : Sending file: filename.) . Or rather as it is in the code from line 17360 in dgate.cpp

OperatorConsole.printf("Sending file : %s\n", Filename);

I'd like to put something like

OperatorConsole.printf("UPACS THREAD %d: Sending file : %s\n", Threadnum, Filename);

Would that be possible? Thanks in advance.

Mr Johnathan Bravo

Marcel

or anyone who might have done this already.

Would there be anything inherently wrong with running multiple dgate instances pointing to the same mysql database? Would there be anything to watch out for in a setup like this assuming it's sane besides making sure both dgates point to the same MAG location?

Hi,

Sorry, an error in the makefile; add $SRC/luasocket/luasocket.a into line 47 in maklinux just as in line 39.

Note: fixed in 1.4.19c1

Marcel

Just as a quick note, I also just compiled on a fresh Centos 7.6 with the newest 1419c1 download and the $SRC/luasocket/luasocket.a is not in line 39 and so making with Mysql option doesn't work until it's added back into line 39. It is however in line 47.

On a fresh install of CentOS 7.4 I'm attempting to compile dgate with the maklinux script. I'm currently receiving the following error on compile.

In file included from ./src/dgate/src/total.cpp:116:0:./src/dgate/dicomlib/qrsop.cxx: In member function ‘BOOL StandardRetrieve::Read(PDU_Service*, DICOMCommandObject*)’:./src/dgate/dicomlib/qrsop.cxx:314:53: error: ‘min’ was not declared in this scope        0xff00, min(ADDO.GetSize() - Index - 1, 65535),

resolved by adding

#define min(a, b) ((a)<(b)?(a):(b))

to the beginning of ./src/dgate/dicomlib/qrsop.cxx

also from the jpeg-6c configure (run from maklinux)
on Centos 7.4

/usr/bin/install -c -m 644 ./cjpeg.1 /usr/local/man/man1/cjpeg.1

should be

/usr/bin/install -c -m 644 ./cjpeg.1 /usr/local/share/man/man1/cjpeg.1

I know the above is more distro specific but possibly adding a call to manpath in the configure script might resolve the issue more permanently.

I've been adding some instance data to the DICOMImages table using dicom.sql . All is going well except that I cannot get specific tag to load when sending dgate an image. The tag in question is defined in dicom.sql *Image* section as below:

{ 0x0008, 0x1155, "ReferencedSOPInstanceUID", 64, SQL_C_CHAR, DT_UI},

I have a corresponding database field as such:

Referenced` varchar(64) DEFAULT NULL

I know that this tag is generally part of a sequence within the image file but i didn't think that would have been an issue. When running a debug log I see all the other fields defined in the "Add to Table: DICOMImages" but not the one above. Could you advise please.

Thanks in advance
Mr Johnathan Bravo

Marcel
ok. thanks.

I ran a dgate --deletestudy:Studyuid recently and the actual image files were deleted but the DB entries were not. I received the following for each image in the log.

***Could not remove IOD /data/216584/1.2.3.4.5.6445443.5.4.dcm

***[NewDeleteFromDB] -FAILED: DDO does not contain correct UIDs

Could you let me know what this is telling me ?

Thanks.

in the windows manual , in appendix 5 you have a listing of all the options for dgate. I was wanting to use the configuration options related to the ACRNEMA.MAP file. However I can't figure out the command. In the text you list something like the following:

--get_amap:index,fmt              List any entry from ACRNEMA.MAP

however I can't seem to find any reference to what "index" or "fmt" are supposed to be.
Could you point me to where i could find find that information?
or one of the other ones like

--put_amap:i,AE,ip,p#,cmp

I can figure out AE and IP but the others I'm not so sure.
Can you assist

Just to help .
on line 52 I had to add the full path to the dgate directory so

local logroot     = "/usr/local/dgate/DicomAnonymized_Log/"

and also I had changed line 79 . the open mode was set to "wt" , and I think it should be "w+" as I could not find any reference in lua documentation on line for a "wt" mode . I also added the assert so I could see the error on the file open.

local f = assert(io.open(logdir .. logfile, "w+"));

Hope this helps.

I am still seeing the error . However by adding the entire path to lua script as in:

/dgate --modifystudy:,1.2.3.1212.1232,"/usr/local/dgate/lua/anonymize_script.lua('199199')"

I was able to produce a different error. This was

lua run error /usr/local/dgate/lua/anonymize_script.lua:80: attempt to index local 'f' (a nil value) in 'dofile('/usr/local/dgate/lua/anonymize_script.lua')'

Any other hints or suggestions .
Thanks for looking reviewing this post .

Hello

I've been attempting to use the lua/anonymize_script to do some anonymization of studies. Unfortunately I can't get it to work and I'm not entirely sure why. I'm using the following form

/dgate --modifystudy:,1.2.3.1212.1232,"lua/anonymize_script('199199')"

after running this from a bash cmd line I get the following in the serverlog

Importconverter-1.0 error: lua/anonymize_script

I do have lua installed and up to date. I've also tried several other changes in syntax like escaping the single quotes, giving the full path to the script, removing the double quotes altogether but they all result in the same error.
Does anyone have any suggestions.
BTW running dgate 1.4.19 on centos 7.3

Thanks in advance

Marcel

Ahh.. ok. I didn't realize that. Mostly was looking to add a "fill up worklist" button using the query on query/move. No biggie though I'll just write it externally on a web page or something.
Thanks.
