Hi all,

We are trying to migrate data from a pacs to Xnat using  dicom send from the pacs to a Xnat scp receiver port. 

What we are trying to accomplish are the following things:
1) Assign a project when there is a match on a Patientname. Included is part of a ctp script as an example. The reason why we cannot use CTP because the subjects in the pacs contain segmentation data. CTP can't read segmentation dicom files.

<script>
  <e en="T" t="00324000" n="StudyComments">@always()@if(PatientName,contains,"A"){Project:ProjectA;Subject:@contents(PatientName);Session:@contents(PatientID)}
{
@if(PatientName,contains,"B"){Project:ProjectB;Subject:@contents(PatientName);Session:@contents(PatientID)-@hash(SeriesInstanceUID,2)}
}
}
</e>
</script>

2) One research project on the pacs has spaces in de patientname. We would like to replace the spaces with a _ and then assign a project to the data. 

With kind regards.

Hi Martin,

I can't claim I'm exactly following what you mean, but it sounds too complicated for the built-in custom routing. I think the only real choice would be writing a custom DICOM object identifier in a plugin. We don't have any documentation on this, but I can point you at an example: https://bitbucket.org/xnatdev/dicom-query-retrieve/src/304a7ab7f0e41f6885fb4eda879393bc6d535efe/src/main/java/org/nrg/xnatx/dqr/DicomQueryRetrievePlugin.java#lines-75 . Hopefully that helps a bit.

Thanks,
Charlie

Hi Charlie,

Thank you for your reply. What we would like to automate is the following. When a dicom session is send to xnat it is automatically put in the pre-archive. 
In the pre-archive you can attach a project to the dicom session.

For one project we need to get rid of the spaces in the patientname dicom header before we attach a xnat project. 

With kind regards,

Martin

Hi Martin,
 if it might help for the elimination of spaces in patient names, 
 the following lines in a dicom edit script (.das) seem to work in replacing spaces and slashes with _ 

tempId := (0010,1001)
(0010,1001) := replace[ replace[ tempId, " ", "_" ], "/", "_" ]

it will probably also work as a one-liner:
(0010,1001) := replace[ replace[ (0010,1001), " ", "_" ], "/", "_" ]
but I haven't verified that.

Hi Paul,

Thank you for your reply.

We added this line in Project Routing (Site Wide) section.

(0010,0010):.*(?i)(project1).*:1 t:(?i)project1 r:pr1

In the Subject Routing (Site Wide) section
The code below changes the space into a _
(0010,0020):ROBINSCA\s.* t:\s r:_ 

With kind regards,

Martin
