[help]What is the solution for handle missing 'Transfer Syntax UID' after v3.0 droped fix_meta_info()?

[Cherrymelon]

I found some dicom will raise missing 'Transfer Syntax UID' when I read dicom.pixel_array.
I have to downgrade pydicom to v2.4,but if I want to use v3.0 what should I do? copy fix_meta_info method as local code?

You should set the correct transfer syntax in the dataset's file_meta:

from pydicom import dcmread
from pydicom.uid import ExplicitVRLittleEndian  # or whatever the actual transfer syntax is

ds = dcmread(...)
ds.file_meta.TransferSyntaxUID = ExplicitVRLittleEndian  # or whatever the actual transfer syntax is

Also, going off the warning it looks like the dataset's SOP Class UID is using a text description rather than the actual UID...

from pydicom.uid import SecondaryCaptureImageStorage

# This
ds.SOPClassUID = SecondaryCaptureImageStorage
# Or this
ds.SOPClassUID = "1.2.840.10008.5.1.4.1.1.7"
# Not this
ds.SOPClassUID = "Secondary Capture Image Storage"
