Hi all!

Got a two studes from SIEMENS MAGNETOM MR.
When try upload to orthanc got an errors
34446656 Bad file format - via Orthanc Explorer 2
and via Orthan.log file:
E0709 10:09:34.000458 HTTP-7 OrthancException.cpp:62] Bad file format: Cannot parse an invalid DICOM file (size: 146846 bytes)
Meanwhile these studies not open via Weasis, but oopens normally via MicroDicom
Hello,
Your files are simply totally invalid with respect to the DICOM standard, as shown by the standard dciodvfy
command-line tool:
$ dciodvfy 34447327
(0x0021,0x105c) ? - Warning - Unrecognized tag - assuming explicit value representation OK
(0x0021,0x1188) ? - Warning - Unrecognized tag - assuming explicit value representation OK
(0x0021,0x118a) ? - Warning - Unrecognized tag - assuming explicit value representation OK
Error - Tag read failed
Error - Dicom dataset read failed
[...]
So, please get in touch with the technical support of Siemens (you pay a contract maintenance for your Siemens Magnetom MR modality). It is up to Siemens to make sure that their DICOM files are standard compliant.
Regards,

Siemens Ukraine usually told “It’s your side problem” 
Unfortunately, if Siemens doesn’t produce valid DICOM files, it is not Orthanc’s problem either
