* Have a pair of Orthanc servers knowing of each other's AET, call one PACS, the other one PEER
* get a sample DICOM study
* create a modified study for different PatientID, but with the same StudyInstanceUID
* upload both studies to the Orthanc PACS using POST /instances (this should probably fail but does not)
* initiate C-MOVE of either study to the PEER instance via PEER HTTP API. This seems to succeed but fails silently without moving any data over. PACS instance shows:

IMoveRequestHandler Failed: Bad request 

Note that the HTTP request (POST /queries/5e9573d4-391f-4c9f-a52b-dfb250323b4b/retrieve, with body PEER) responds with 200.

This can also be reproduced via the WEB UI Query/Retrieve.

Debugged this further today by inspecting query-series of the original query. Each of the two patients should have exactly one study but even when querying for one of the patients, both are matched. To illustrate, notice the search was for a patient ID but the matched series belong to different patients:

Please could you provide sample DICOM files, possibly anonymized, to reproduce your issue? TIA.

Hi Sebastien, I can reproduce the problem using the DICOMs attached. Each folder in the archive is one patient.

Hi Sebastian, testing this on 1.5.6 the problem still exists.

From my understanding of your issue, it is solved in Orthanc 1.5.6. 

\(1\) Let’s create 2 configuration files:

```
$ mkdir /tmp/i
$ cd /tmp/i
$ cat << EOF > a.json
{
  "DicomAet" : "PEER",
  "DicomPort" : 4242,
  "HttpPort" : 8042,
  "DicomModalities" : {
    "pacs" : [ "PACS", "localhost", 4343 ]
  },
  "StorageDirectory" : "a"
}
EOF
$ cat << EOF > b.json
{
  "DicomAet" : "PACS",
  "DicomPort" : 4343,
  "HttpPort" : 8043,
  "DicomModalities" : {
    "peer" : [ "PEER", "localhost", 4242 ]
  },
  "StorageDirectory" : "b"
}
EOF
```

\(2\) Let’s start Orthanc on those 2 configuration files in two separate terminals:

```
$ cd /tmp/i
$ ~/orthanc/Build/Orthanc a.json --verbose
```

```
$ cd /tmp/i
$ ~/orthanc/Build/Orthanc b.json --verbose
```

\(3\) Let's upload the content of your `dupes.zip` sample to Orthanc “a”:

```
$ ~/orthanc/Resources/Samples/ImportDicomFiles/ImportDicomFiles.py localhost 8043 /tmp/dupes/
```

\(4\) Check that Orthanc “a” is empty, but that Orthanc “b” contains your two instances:

```
$ curl http://localhost:8042/instances/
[]
$ curl http://localhost:8043/instances/
[
   "669397d9-6fe43fe9-c96967ee-a5a954c7-d2d8a5f8",
   "dbae414e-ae8edea3-b83daad1-648d14e9-9714a24b"
]
```

\(5\) Make Orthanc “a” \(on port 8042\) drive a query/retrieve from Orthanc “b”:

```
$ curl http://localhost:8042/modalities/pacs/query -d '{"Level":"Study", "Query": {"PatientID": "3339910"}}'
{
   "ID" : "876ee677-2397-46a3-b813-545c790eb35f",
   "Path" : "/queries/876ee677-2397-46a3-b813-545c790eb35f"
}
$ curl 'http://localhost:8042/queries/876ee677-2397-46a3-b813-545c790eb35f/answers?expand&simplify'
[
   {
      "AccessionNumber" : "B7360694",
      "PatientID" : "3339910",
      "QueryRetrieveLevel" : "STUDY",
      "SpecificCharacterSet" : "ISO_IR 100",
      "StudyInstanceUID" : "1.2.276.0.7230010.3.1.4.3942190661.3348.1548665123.1020.3339910"
   }
]
$ curl http://localhost:8042/queries/876ee677-2397-46a3-b813-545c790eb35f/retrieve -d 'PEER'
{
   "Description" : "REST API",
   "LocalAet" : "PEER",
   "Query" : [
      {
         "0008,0050" : "B7360694",
         "0008,0052" : "STUDY",
         "0010,0020" : "3339910",
         "0020,000d" : "1.2.276.0.7230010.3.1.4.3942190661.3348.1548665123.1020.3339910"
      }
   ],
   "RemoteAet" : "PACS"
}
```

\(6\) Check that Orthanc "a" has correctly received the 2 instances of `dupes.zip`:

```
$ curl http://localhost:8042/instances/
[
   "669397d9-6fe43fe9-c96967ee-a5a954c7-d2d8a5f8",
   "dbae414e-ae8edea3-b83daad1-648d14e9-9714a24b"
]
```

From my point of view, this is a correct behavior in the presence of ill-conditioned DICOM data.

Sebastian, thanks for following up. Does that mean that both the retrieving and sending instance need to be on Orthanc 1.5.6? I can still reproduce the error with an old “PACS side” but a 1.5.6 receiving side.

Your issue was present in the C-MOVE SCP \(not in the C-STORE SCU\). In other words, your “sending Orthanc” \(aka. “PACS-side”\) must be at version >= 1.5.6 to benefit from the fix. The version of the “receiving Orthanc” \(aka. “PEER”\) has no importance.
