ValueError: could not convert string to float #63

Closed hamiltonjp closed 1 year ago

Greetings--

Just trying out dcmstack --embed-meta option with a 4D dataset (3 space, one time) comprising many 2D DICOM slices acquired on a new Siemens Prisma 3T scanner. See attached compressed sample DICOM slice...

When I run: dcmstack --embed-meta ./DICOM_dir I get the error: ValueError: could not convert string to float: Amadeus

In this case, the string Amadeus has been used by our MRI sysadmin to anonymize various patient-identifying fields such as: StudyDescription: 'Amadeus' PatientID: 'Amadeus' PatientBirthDate: 'Amadeus' PatientSex: 'Amadeus' PatientAge: 'Amadeus'

Any help?

Tusen tack from Sweden...

When anonymizing DICOM files, the placeholder values should still be valid for the VR of the element. For example when anonymizing dates I will typically use 19000101 or something similar.
