DICOMAnonymizer Failure

[Nick Bevins]

Greetings-

I'm running into an issue with a single DICOM study that can't get through the anonymization step. Here is the section of the log that I think is relevant:

08:41:15 INFO  [DICOMAnonymizer] Unknown exception from GBM\roots\DicomImportServiceGBM\active\QF-5125908384406722313.dcm
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
	at java.lang.String.substring(Unknown Source)

	at org.rsna.ctp.stdstages.anonymizer.dicom.DICOMAnonymizer.anonymize(DICOMAnonymizer.java:167)

	at org.rsna.ctp.pipeline.Pipeline.processObjects(Pipeline.java:220)
	at org.rsna.ctp.pipeline.Pipeline.run(Pipeline.java:181)

Any ideas?

Thanks

Nick:

 

This looks like a bug.

 

The failure is occurring when the anonymizer's script parser tries to obtain the name of a function to call in one of the element scripts. Unfortunately, the stack trace doesn't say which element. The parser is expecting a delimiter to terminate the name, and it isn't finding it.

Does this script really run correctly for other images?

 

Can you send me the image and your anonymizer script?

Dear John,

Were you able to identify the issue documented in this conversation?

We are having the same problem on some PT series:
