Deleting a Series

[Dev G]

I am pretty new to DCM4CHE, so this may be a simple question.

Is there a way to delete a Series using a program (without using the GUI) using the instance UID?

Alternately, is there a way to replace an existing series with a changed DICOM file using a program? When I tried doing this using DcmSnd, it created tow instances.

thanks

There is only a deleteSeries method in the content edit service but it needs the PK from the database as parameter.

[Dev G]

Thanks for the info. I think I can get the PK from the database. Can you tell me how I can call the method?

Thanks

You can use the twiddle script in the dcm4chee/bin folder - there are examples how to use on this forum.

[Dev G]

Sorry took so long to get back. I tried calling the deleteSeries method in the edit service using the twiddle script, but it does seem to do anything. See below:

$ /home/pacs/dcm4chee-2.18.0-mysql/bin/twiddle.sh -uadmin -padmin invoke dcm4chee.archive:service=ContentEditService moveSeriesToTrash 183
$ echo $?
1

183 is pk from the series table in pacsdb. The status return is 1, saying failed and series is still there.

Any idea what I am doing wrong?

Thanks

any output in dcm4chee's server.log ?

[Dev G]

No output at all.

BTW I also tried
$ /home/pacs/dcm4chee-2.18.0-mysql/bin/twiddle.sh -uadmin -padmin invoke dcm4chee.archive:service=ContentEditService deleteSeries183

with the same result

hmm !

maybe you also need to move it first to the trash (i remember that I had to do this for some reason using the contenteditservice)

[Dev G]

I did try to move it to trash first and it did not work either. No log or error in server.log.

Anyway, I think I see the problem there two moveSeriesToTrash methods in the service. I think the server has a problem figuring it out which one to call. It may be calling the wrong one (but then it should at least log an error).

I will try compiling from source and renaming one of the methods for now, until it gets fixed in the next version.

Thanks

Hi
I have the same problem:
twiddle.sh -u admin -p admin invoke "dcm4chee.archive:service=ContentEditService" moveSeriesToTrash 24
does not work
using jmx-console works fine

Dev, does renaming fixed the problem ?

EDIT:
something else about diffrent between delete and moveToTrash
using deleteSeries I have: "javax.ejb.ObjectNotFoundException: No such entity!"
but I'm sure I have such entity, so checked pg_log:

SELECT t0_Series.pk FROM series t0_Series WHERE t0_Series.pk=$1           -- this is when invoking moveSeriesToTrash (using jmx)
SELECT t0_PrivateSeries.pk FROM priv_series t0_PrivateSeries WHERE t0_PrivateSeries.pk=$1        -- this is when invoking DeleteSeries (using jmx)

what kind of data is in priv_series ? is it trash for series ?

[Dev Gude]

Yes, I renamed the second function to moveSeriesToTrash2 and rebuilt dmc4chee.jar, then the twiddle script worked.

Can't find this function by name. Could You give me more detailed tip where You found it?

For anyone wondering how to actually do this without recompiling DCM4CHEE and renaming methods...

twiddle.sh -u user -p password serverinfo -l | grep ContentEditService

dcm4chee.web:service=ContentEditService

dcm4chee.archive:service=ContentEditService

If you examine dcm4chee.web:service=ContentEditService you'll see this also contains a moveSeriesToTrash method - it takes two parameters.

Get the SeriesUID you want to delete and replace it in the command below.

twiddle.sh -u user -p password invoke 'dcm4chee.web:service=ContentEditService' moveSeriesToTrash SeriesIUID true

You probably also want to clear out the trash after doing this.

twiddle.sh -u user -p password invoke 'dcm4chee.web:service=ContentEditService' emptyTrash

To answer the latter part of the question, if you want to alter a DICOM instance object in the archive directly you can do this using dcmodify or similar. For every file you alter, you also need to update files.file_md5 and files.file_size in the database otherwise DCM4CHEE will be very unhappy and probably won't let you access the study via the web interface or WADO.

In short: Make alterations, compute an MD5 digest, update the database. Depending on how you use the database, you might also want to update a bunch of fields in other tables, consider the attrs fields as well, you might need to regenerate these depending on your circumstances.

Hi,

I want to do a quick modify of SUID on the server using twiddle  . 

The goal is to modify the SUID (Study instance UID) of a study already on PACS, from existing SUID of for example 1.2.34.56.789 to a new SUID of my choice (for example 9.87.654.32.1) without doing this : Download to local drive -> modify -> reupload. 

The DCM4CHEE2 web3 GUI mouse clicking interphase shows editing SUID is achievable quickly on the server side.  However I have not been able to achieve this using commandline (be it twiddle or PHP).   

I checked out dcmodify also, and it works on local DICOM only, not modify the SUID on server. 

My current long workaround is the following:

1. Upload a dummy empty shell new DICOM that is SUID 9.87.654.32.1 and no series, no images.

2. Move all series from 1.2.34.56.789  -> 9.87.654.32.1 by doing: 

jboss-4.2.3.GA\bin\twiddle.bat -s localhost -u admin -p admin invoke dcm4chee.web:service=ContentEditService moveSeriesToStudy  1.2.34.56.789   9.87.654.32.1

3. Delete 1.2.34.56.789 by doing:

jboss-4.2.3.GA\bin\twiddle.bat -s localhost -u admin -p admin invoke dcm4chee.archive:service=ContentEditService moveStudyToTrash 1.2.34.56.789

Thanks in advance.
